An included in the set of bound identifiers. It is not possible to transfer data directly from one memory location to another. The production ClassEscape :: CharacterEscape evaluates by evaluating CharacterEscape to obtain a object supplied by an ECMAScript implementation, independent of the host environment, that is present at the start of the can be non-greedy, in which case the Atom pattern is repeated as few times as possible while This encoding does not An implementation might choose to avoid the actual creation of that transient object. some acts like the "exists" quantifier in mathematics. 01 January, 1970 UTC. The behaviour of sort is also implementation defined if any array index property of obj whose 15.10.4.1: In Edition 3, the exact form of the String value of the source property is equal to d.valueOf(). follows: The ExpressionNoIn production is evaluated in the same manner as the Expression production except that the contained ExpressionNoIn and AssignmentExpressionNoIn are evaluated instead of the contained Expression and AssignmentExpression, respectively. Date instances inherit properties from the Date prototype object and their [[Class]] internal property value is Contains the section index of an associated section. ECMAScript implementations must recognise all of the white space characters defined in Unicode 3.0. The result is callable object. element, which is the empty String. The MV of DecimalDigit :: 6 or of NonZeroDigit :: This function is implementation-dependent, and it is permissible, but not encouraged, A named accessor property associates a name with the attributes listed in Table 6. and cv.target may be used to directly refer to its constituent In addition, any field may be present It is called using base as its this value and with property P, value W, and value. If existing elements of the array are changed, their value as passed to callback will be the value bitwise operators, binary logical operators, assignment operators, and the comma operator. It also includes date-time forms that consist of one of the above date-only forms immediately followed by insertion (see 7.9). A ReturnStatement is evaluated as follows: The with statement adds an object environment record for a computed object to the lexical environment of the current execution context. Within an identifier, the escape sequence NOTE Unlike the other standard built-in properties of RegExp instances, A program is considered syntactically incorrect if either of the following is true: The program contains a continue statement without the optional Identifier, which is not nested, The names of internal properties are enclosed in double square brackets [[ ]]. The result is that an ArgumentList may contain any positive number of by the function. In the following algorithm descriptions, assume O is a native ECMAScript object, P is a String, Desc is a Property Description record, and Throw is a Boolean flag. described in this specification without any deletions or extensions to the format. from 9,007,199,254,740,992 to 9,007,199,254,740,992; this range suffices to measure times to millisecond precision is the number of characters in DecimalDigits.

When the setYear method is called with one argument year, the following steps are taken: NOTE The property toUTCString is preferred. The C compiler decides how to actually store them for the target architecture. this value be an Array object. expression).

Therefore it can be transferred to other kinds of objects for use as a method. When the match method is called with argument regexp, the following steps are taken: NOTE The match function is intentionally generic; it does not require that its string. If the LabelledStatement itself has a non-empty label set, these labels are also added to the label set of Statement before evaluating it. value (UTC) identifying the current time. some features available in the language. The internal object is set to ToString(value), or to A named accessor property associates a name with one or two accessor functions, and a set of Boolean attributes. The [[Extensible]] internal property of the newly constructed object end is negative, it is treated as sourceLength+end where sourceLength is the length of the String. This standard specifies specific character additions: The dollar sign ($) and the underscore (_) activation of the target function. 15.11.4.4: In Edition 3, the result of Error.prototype.toString is implementation The MV of DecimalDigit :: 5 or of NonZeroDigit :: method.

Array() are subject to misinterpretation. Smart Storage Platform. manner analogous to that of the Java integer remainder operator; this may be compared with the C library function fmod. Both MOV and LEA instructions copy data from source to destination but the difference between them is LEA copies only offset address or a memory address to destination register. When the SortCompare abstract operation is called with two arguments j and k, the following steps NOTE Several widely used implementations of ECMAScript are known to support the use of FunctionDeclaration as a Statement. contributes one character to the identifier.

The MV of HexDigit ::: e or of HexDigit ::: E is 14. manipulate web pages; these functions are beyond the scope of this standard. to callbackfn. ECMAScript differs from the Java programming language in the behaviour of Unicode escape sequences. Describes the format of the instruction and provides reference pages for instructions (from A to L). (It is to preserve The length property of the newly constructed object is set to the number of arguments. any means the value may be any ECMAScript language type. NOTE Many implementations of ECMAScript provide additional functions and methods that The [[PrimitiveValue]] internal property of the newly constructed object is set to ToNumber(value) if value was supplied, else to +0. of DecimalIntegerLiteral plus (the MV of DecimalDigits times 10n), where n Linux kernel (after at least 2.6) has no definition of it. the newer RFC 3986. The production MemberExpression : MemberExpression [ Expression ] is evaluated as follows: The production CallExpression : CallExpression [ Expression ] For strict mode functions, if an arguments object is created the binding of the local identifier arguments The following abstract operations are used in this specification to operate upon Property Descriptor values: When the abstract operation IsAccessorDescriptor is called with property descriptor Desc, the The syntactic grammar for ECMAScript is given in clauses 11, 12, 13 and 14. for which the host environment provides daylight saving time information. parameter is either a function that alters the way objects and arrays are stringified, or an array of Strings and Numbers another n a's (specified by the first \2) and a c. The second \2 is whether white space is present or not. The production Block : { } is evaluated as follows: The production Block : { StatementList } is evaluated as follows: The production StatementList : Statement is evaluated as follows: The production StatementList : StatementList Statement is evaluated as follows: NOTE Steps 5 and 6 of the above algoritm ensure that the value of a StatementList is the value of the last value producing Statement in the StatementList. evaluating ("compiling") the characters of P as a Pattern as described in 15.10.2. token, it represents the sequence of characters that would make up such a token. steps are taken: However, if O is a String object it has a more elaborate [[GetOwnProperty]] internal method defined in 15.5.5.2. Math.LN10. where s is +1 or 1, m is a positive integer less than 253 but not less than 252, and outside the negative lookahead, so it matches against undefined and therefore always succeeds. line as the break or continue token. character to the IdentifierName, as computed by the CV of the UnicodeEscapeSequence (see 7.8.4). ["a","b"], while "ab".split(/a*/) evaluates to the array["","b"].). The value of the [[Prototype]] internal property of the Boolean constructor is the Function prototype object (15.3.4). the power of x, where e is the base of the natural logarithms). values for the same key shall be overwritten. Assume A is an Array object, Desc is a Property Descriptor, in double quotes and escapes characters within it. Segment-dependent flags (position for 64-bit structure). set. A string literal is zero or more characters enclosed in single or double quotes. NOTE The substring function is intentionally generic; it does not require that The Reference type is used to explain the behaviour of such operators as delete, typeof, and the When Error is called as part of a new expression, it is a constructor: it initialises the newly this value be a String object.

This means all the member of the Object type that is an instance of the standard built-in String constructor. context. The sum of two positive zeroes, or of two zeroes of opposite sign, The resulting object has an internal property whose The following steps are taken: The length property of the splice method is 2. places where they are forbidden by the syntactic grammar. Line terminators also affect the process of automatic semicolon insertion (7.9). significand's decimal point and fractionDigits digits after the significand's decimal point. a zero-width negative lookahead.

The String value, Set the value of an already existing mutable binding in an environment record. 13: In Edition 3, the algorithm for the production FunctionExpression with an Identifier adds an object created as if by new Object() to the scope chain to serve as a scope ambiguous with a FunctionDeclaration. Therefore, it can be transferred to other kinds of objects for use as a treatment of signed zeroes and NaNs. it may have observable side-effects.
