JavaScript syntax 18 JavaScript syntax This article is part of the JavaScript series. JavaScript JavaScript syntax JavaScript topics The syntax of JavaScript is the set of rules that define a correctly structured JavaScript program. Note: The examples below make use of the alert function for standard text output. The JavaScript standard library lacks an official standard text output function. However, given that JavaScript is mainly used for client-side scripting within modern web browsers, and that almost all web browsers provide the alert function, alert is used in the examples. Origin of Syntax Brendan Eich summarized the ancestry of the syntax in the first paragraph of the JavaScript 1.1 [1] specification as follows: JavaScript borrows most of its syntax from Java, but also inherits from Awk and Perl, with some indirect influence from Self in its object prototype system. Syntax Basics Case sensitivity JavaScript is case sensitive. It is common to start the name of a constructor with a capitalised letter, and the name of a function or variable with a lower-case letter. Whitespace and semicolons Spaces, tabs and newlines used outside of string constants are called whitespace. Unlike C, whitespace in JavaScript source can directly impact semantics. Because of a technique called "semicolon insertion", some statements that are well formed when a newline is parsed will be considered complete (as if a semicolon were inserted just prior to the newline). Programmers are advised to supply statement-terminating semicolons explicitly, although it degrades readability, because it may lessen unintended effects of the automatic semicolon insertion.
