• Label Statement: JavaScript Term
The label statement works in conjunction with the break and continue statements. The label statement is a JavaScript statement with a label. By labeling a statement, you give it a name that you can reference (with break and continue statements) from elsewhere in your program. Syntactically, a label consists of an identifier followed by a colon. It is the colon that tells the interpreter that the identifier is a label. Label names will not be confused with normal identifiers. Names of labels do not exist as properties on a Call object but, instead, are added to a label set. The label set is a pool of all program labels and acts as a destination reference (where to jump) for break and continue label references.

• lang Selector: CSS Selector
The pseudo-class lang selector gives us the ability to write selectors that match elements based on the human language of the document. See selector patterns for formats. Language codes are inherited from a number of sources and the inheritance has a precedence. With an HTML document, the inheritance follows this sequence (from highest precedence to lowest):
  • the LANG attribute set for the element itself
  • the closest parent element that has the LANG attribute set
  • the HTTP "Content-Language" header
  • UA default values and user preferences


• Latin-1 Character Set (ISO-8859-1): Web
The Latin-1 character set is the same as the ISO-8859-1 character set. The first half of the character set is the standard ASCII set ( 0-127 chars ). The second half ( 128-255 ) is the extended ASCII. Together they make up the Latin-1 character set which is the typical character set used on the Web ( US of A ). Note that the 255 character Latin-1 parallels the first 255 characters of the Unicode standard.

• Left Shift Operator: JavaScript Operator
The left shift operator ( symbol: << ) is a binary operator with integer operands. It shifts all bits of the first operand to the left by the number specified in the second operand. The left shift preserves the sign of the original number. In other words, the sign bit ( 32nd bit ) is not affected by the shift, however, the 31st bit will be shifted out ( lost ) with each positioned shifted. The second operand should be an integer between 0 and 31.
The attributes of this operator are:

• Less Than and Less Than or Equal Operators: JavaScript
The less than operators ( symbols: < and <= ) are binary operators with either number or string operands. The less than operator evaluates to true when its first operand is less than its second operand. Otherwise, it evaluates to false. Numbers are compared numerically. Strings are compared based on character ASCII values.
The attributes of this operator are:

CSS provides two pseudo-classes selectors,":link" and ":visited", that together are called the link selectors. The link selectors provide an easy method of distinguishing between the two states (link and visited). The states (link or visited) are mutually exclusive. See selector patterns for formats. Any element with an "href" attribute will exhibit one of the two states and the UA s responsible for keeping track of all hyperlinks visited status. These two selectors are described here:
  • :link applies to links that have not yet been visited
  • :visited applies to links that have been visited


• list-style-image Property: CSS Property
The list-style-image property specifies the image that will be used for the list item marker. This property will override the 'list_style_type' marker when both properties are specified. The keyword 'url' is a special method of CSS. The value inside the parenthesis (the parameter to the url method) is a string that represents an URI of the CSS <uri> data type.
list-style-image:
Value: <uri> | none | inherit
Initial: none
Applies to: elements with 'display list-item'
Inherited: yes
Percentages: N/A
Media: visual
Computed Value: an absolute URI or none
Style Group: Generated Content
Deprecated: no
Example: ul { list-style-image: url(http://freeart.com/peanut.png); }


• list-style-position Property: CSS Property
The list-style-position property specifies the position of list markers. CSS can insert list markers or images and position such content relative to the list items. The 'outside' value specifies the marker box is outside the principal block box. The 'inside' value specifies the marker box is the first inline box in the principal block box.
list-style-position:
Value: inside | outside | inherit
Initial: outside
Applies to: elements with 'display list-item'
Inherited: yes
Percentages: N/A
Media: visual
Computed Value: as specified
Style Group: Generated Content
Deprecated: no
Example: ul { list-style-position: inside; }


• list-style-type Property: CSS Property
The list-style-type property describes formatting of lists by generating a marker type. The markers can be of a glyphs type, a numbering system type or an alphabetic system type. The CSS list properties are included in the Generated Content Style Group because the marker is content generated under the control of CSS.
list-style-type:
Value: disc | circle | square | decimal | decimal-leading-zero | lower-roman |
upper-roman | lower-greek | lower-latin | upper-latin | armenian |
georgian | lower-alpha | upper-alpha | none | inherit
Initial: disc
Applies to: elements with 'display list-item'
Inherited: yes
Percentages: N/A
Media: visual
Computed Value: as specified
Style Group: Generated Content
Deprecated: no
Example: ol { list-style-type: decimal-leading-zero; }


• list-style (Shorthand) Property: CSS Property
The list-style property is a shorthand property that will encompass all three of the list properties for the generated content style group. The property values can be expressed in any order when using the shorthand property. Also, the initial value is used when any of the property values are not explicitly expressed. The 'list-style-type' property is subordinate to the 'list-style-image' property, thereby, if both are specified, the image takes effect. But, if the image can not be rendered for any reason, then the 'list-style-type' value will take effect.
list-style:
Value: [ <list-style-type> || <list-style-position> || <list-style-image> ]| inherit
Initial: see individual properties
Applies to: elements with 'display list-item'
Inherited: yes
Percentages: N/A
Media: visual
Computed Value: see individual properties
Style Group: Generated Content
Deprecated: no
Example:    ul { list-style: lower-roman inside; }


• Literal: JavaScript Token
A literal is a value (token) encoded directly in the program code. Each of the JS data types, both reference type and primitive types, have a unique literal syntax. In fact, it is via the literal syntax that the weakly typed JS variables are associated with a data type. The JS regular expressions have a special literal syntactical scheme for expressing regular expression patterns.

• Literal JavaScript RegExp
Refer to RegExp Literals.

• Literal Characters JavaScript RegExp
Regular expressions are comprised of literal characters and meta characters. Literal characters in JavaScript regular expressions are the normal set of alphanumeric characters and some ASCII control characters. The alphanumeric set that applies to JavaScript regular expressions are the combined set of all letters in the alphabet (both upper and lower case) and the numbers 0 through 9. In a regular expression matching operation, the literal characters match to their counterparts in the target string literally.

• Literal Statement JavaScript Statement
The literal statement is comprised of a literal token, an assignment operator and a target variable. The literal is assigned to the variable. During the assignment, the JS interpreter determines the appropriate data type for the target variable.

• Local Scope JavaScript Variables
Variables that are declared inside a function will have local scope as long as the var keyword is used with the declaration statement. Local scope indicates that the variable is visible only to the immediate container function. A variable declared without the var keyword always has global scope regardless of where in the program it is declared.

• Local Time: JavaScript Date & Time
This is the date and time of the time zone of your current location. Hopefully, the local time is currently registered in the computer clock of your machine.

• Logical Operator Group: JavaScript Operator
The logical operator group includes both the logical AND operator and the logical OR operator The ECMAScript term of these two operator is binary logical operators.

• Logical AND Operator: JavaScript Operator
The logical AND operator ( symbol: && ) is used extensively in loop control statements. Both operands are evaluated to a boolean value and the logical AND operation is applied by the operator. The logical AND returns a boolean based on the boolean truth table criteria.
The attributes of this operator are:

• Logical OR Operator: JavaScript Operator
The logical OR operator ( symbol: || ) is used extensively in loop control statements. Both operands are evaluated to a boolean value and the logical OR operation is applied by the operator. The logical OR returns a boolean based on the boolean truth table criteria.
The attributes of this operator are:

• Logical NOT Operator: JavaScript Operator
The logical NOT operator ( symbol: ! ) is a unary operator and placed before a boolean operand. The logical NOT operator will invert the boolean value of its operand ( the logical complement ). For example, if the boolean operator evaluates the unary expression to be true, the operator returns false.
The attributes of this operator are:

• lvalue: JavaScript Operand
The term lvalue stands for "lefthand side" value. It pertains to the legal expressions that can appear on the lefthand side of an operator. In JavaScript, elements of arrays, variables and properties are legal lvalues for applicable operators. The lvalues generally ( but not exclusively ) relate to assignment operators. The lvalue operand type exists for some unary operators, so the "L" in lvalue is not so descriptive with JavaScript.

• lvalue Operand: JavaScript Operators
The lvalue operand is an operand that takes a lvalue. Typically, the lvalue operand refers to the identifier that is used on the left-hand-side of an assignment operation. But it is also applicable in the increment/decrement operators and the delete operator.
