A conforming implementation of this Standard shall interpret characters in conformance with the Unicode Standard, Version 3. If the adopted encoding form is not otherwise specified, it presumed to be the UTF encoding form.

A conforming implementation of ECMAScript is permitted to provide additional types, values, objects, properties, and functions beyond those described in this specification.

Partial types

In particular, a conforming implementation of ECMAScript is permitted to provide properties not described in this specification, and values for those properties, for objects that are described in this specification. A conforming implementation of ECMAScript is permitted to support program and regular expression syntax not described in this specification.

ECMAScript is an object-oriented programming language for performing computations and manipulating computational objects within a host environment. ECMAScript as defined here is not intended to be computationally self-sufficient; indeed, there are no provisions in this specification for input of external data or output of computed results.

Instead, it is expected that the computational environment of an ECMAScript program will provide not only the objects and other facilities described in this specification but also certain environment-specific host objects, whose description and behaviour are beyond the scope of this specification except to indicate that they may provide certain properties that can be accessed and certain functions that can be called from an ECMAScript program.

A scripting language is a programming language that is used to manipulate, customise, and automate the facilities of an existing system.

In such systems, useful functionality is already available through a user interface, and the scripting language is a mechanism for exposing that functionality to program control. In this way, the existing system is said to provide a host environment of objects and facilities, which completes the capabilities of the scripting language.

A scripting language is intended for use by both professional and non-professional programmers. ECMAScript was originally designed to be a Web scripting language, providing a mechanism to enliven Web pages in browsers and to perform server computation as part of a Web-based client-server architecture.

ECMAScript can provide core scripting capabilities for a variety of host environments, and therefore the core scripting language is specified in this document apart from any particular host environment. Addison Wesley Publishing Co.

Ungar, David, and Smith, Randall B. The Power of Simplicity. Further, the host environment provides a means to attach scripting code to events such as change of focus, page and image loading, unloading, error and abort, selection, form submission, and mouse actions.

Scripting code appears within the HTML and the displayed page is a combination of user interface elements and fixed and computed text and images. The scripting code is reactive to user interaction and there is no need for a main program.

A web server provides a different host environment for server-side computation including objects representing requests, clients, and files; and mechanisms to lock and share data.

Table of Contents

By using browser-side and server-side scripting together, it is possible to distribute computation between the client and server while providing a customised user interface for a Web-based application. This overview is not part of the standard proper. An ECMAScript object is a collection of properties each with zero or more attributes that determine how each property can be used—for example, when the Writable attribute for a property is set to false, any attempt by executed ECMAScript code to change the value of the property fails.

Properties are containers that hold other objects, primitive values, or functions. A primitive value is a member of one of the following built-in types: Undefined, Null, Boolean, Number, and String; an object is a member of the remaining built-in type Object; and a function is a callable object.

A function that is associated with an object via a property is a method. ECMAScript also defines a set of built-in operators. ECMAScript operators include various unary operations, multiplicative operators, additive operators, bitwise shift operators, relational operators, equality operators, binary bitwise operators, binary logical operators, assignment operators, and the comma operator.

ECMAScript syntax is relaxed to enable it to serve as an easy-to-use scripting language. For example, a variable is not required to have its type declared nor are types associated with properties, and defined functions are not required to have their declarations appear textually before calls to them.

Instead objects may be created in various ways including via a literal notation or via constructors which create objects and then execute code that initialises all or part of them by assigning initial values to their properties.

Objects are created by using constructors in new expressions; for example, new Date ,11 creates a new Date object. Invoking a constructor without using new has consequences that depend on the constructor.

For example, Date produces a string representation of the current date and time rather than an object. Furthermore, a prototype may have a non-null implicit reference to its prototype, and so on; this is called the prototype chain. When a reference is made to a property in an object, that reference is to the property of that name in the first object in the prototype chain that contains a property of that name.Here you will get algorithm and program for evolution of postfix expression in C.

In postfix or reverse polish notation, every operator follows all of its operands. For example: 5 3 2 * + Also Read: Infix to Postfix Conversion in C [Program and Algorithm] Algorithm for Evaluation of Postfix Expression.

Create an empty stack and start scanning the postfix expression from left to right. Learn how to evaluate Postfix expression using Stack in C Programming Language. This C code for postfix evaluation takes in a postfix expression from the user and then evaluates it.

Origins What is the purpose of the project? At the time of Go's inception, only a decade ago, the programming world was different from today. Production software was usually written in C++ or Java, GitHub did not exist, most computers were not yet multiprocessors, and other than Visual Studio and Eclipse there were few IDEs or other high-level tools available at all, let alone for free on the.

Abstract This document provides guidance and an overview to high level general features and updates for SUSE Linux Enterprise Server 11 Service Pack 3 (SP3).

Besides architecture or product-specific information, it also describes the capabilities and limitations of SLES 11 SP3. General documentation may be found at. This product is a VMware tailored and branded version of SUSE Linux. C Program for Evaluation of Postfix ExpressionIn this program we evaluate the Postfix Expression, using the stack.

For example, *+7- is the postfix expression, from left one by one it is inserted into the stack, and after evaluation the answer is Read more about C Programming Language.

The authors present the complete guide to ANSI standard C language programming. Written by the developers of C, this new version helps readers keep up with the finalized ANSI standard for C while showing how to take advantage of C's rich set of operators, economy of expression, improved control flow, and data structures.
