The source text of ECMAScript scripts gets scanned from left to right and is converted into a sequence of input elements which are tokens, control characters, line terminators, comments or white space. ECMAScript also defines certain keywords and literals and has rules for automatic insertion of semicolons to end statements. Control characters Control characters have no visual representation but are used to control the interpretation of the text. White space White space characters improve the readability of source text and separate tokens from each other.

Line terminators In addition to white space characters, line terminator characters are used to improve the readability of the source text. Only the following Unicode code points are treated as line terminators in ECMAScript, other line breaking characters are treated as white space (for example, Next Line, NEL, U+0085 is considered as white space). function comment() { }comment(); Keywords.
