Line 30: ===Whitespace and semicolons=== Unlike in [[C (programming language)\|C]], whitespace in JavaScript source can directly impact [[Semantics (computer science)\|semantics]]. [[Semicolon]]s end statements in JavaScript. Because of "~~automatic~~ [[automatic semicolon insertion]]" (ASI), 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. Some authorities advise supplying statement-terminating semicolons explicitly, because it may lessen unintended effects of the automatic semicolon insertion.<ref>{{cite book \|title=JavaScript: The definitive Guide \|url=https://archive.org/details/javascript00libg_297
