The simplest operation is taking a substring, a snippet of the string taken at a certain offset (called an "index") from the start or end. There are a number of legacy templates offering this but for new code use {{#invoke:String|sub|string|startIndex|endIndex}}. The indices are one-based (meaning the first is number one), inclusive (meaning ...

Additions include JSON, String.trim() to easily remove whitespaces surrounding a string (" example "to "example"), String.charAt() to return a single character from a given position in a string, and Array.isArray().

It is best known as a JavaScript standard intended to ensure the interoperability of web pages across different web browsers. [2] It is standardized by Ecma International in the document ECMA-262 . ECMAScript is commonly used for client-side scripting on the World Wide Web , and it is increasingly being used for server-side applications and ...
In computer science, the Knuth–Morris–Pratt algorithm (or KMP algorithm) is a string-searching algorithm that searches for occurrences of a "word" W within a main "text string" S by employing the observation that when a mismatch occurs, the word itself embodies sufficient information to determine where the next match could begin, thus bypassing re-examination of previously matched characters.
