We believe in a future in which the web is a preferred environment for numerical computation. To help realize this future, we've built stdlib. stdlib is a standard library, with an emphasis on numerical and scientific computation, written in JavaScript (and C) for execution in browsers and in Node.js.
The library is fully decomposable, being architected in such a way that you can swap out and mix and match APIs and functionality to cater to your exact preferences and use cases.
When you use stdlib, you can be absolutely certain that you are using the most thorough, rigorous, well-written, studied, documented, tested, measured, and high-quality code out there.
To join us in bringing numerical computing to the web, get started by checking us out on GitHub, and please consider financially supporting stdlib. We greatly appreciate your continued support!
replace
[![NPM version][npm-image]][npm-url] [![Build Status][test-image]][test-url] [![Coverage Status][coverage-image]][coverage-url]
Replace search occurrences with a replacement string.
bash
npm install @stdlib/string-replace
javascript
var replace = require( '@stdlib/string-replace' );
#### replace( str, search, newval )
Replaces search occurrences with a replacement string.
javascript
var out = replace( 'beep', 'e', 'o' );
// returns 'boop'
If provided a function as the [third argument][mdn-string-replace], the function is invoked for each match, and the function's return value is used as the replacement string.
javascript
function replacer( match, p1 ) {
return '/' + p1 + '/';
}
var str = 'Oranges and lemons';
var out = replace( str, /([^\s]+)/gi, replacer );
// returns '/Oranges/ /and/ /lemons/'
String.prototype.replace
][mdn-string-replace]. When provided a string as the search
value, the function replaces all occurrences. To remove only the first match, use a regular expression.
javascript
var out = replace( 'beep', /e/, 'o' );
// returns 'boep'
javascript
var capitalize = require( '@stdlib/string-capitalize' );
var replace = require( '@stdlib/string-replace' );
var out = replace( 'beep', 'e', 'o' );
// returns 'boop'
out = replace( 'Hello World', /world/i, 'Mr. President' );
// returns 'Hello Mr. President'
function replacer( match, p1 ) {
return capitalize( p1 );
}
var str = 'Oranges and lemons say the bells of St. Clement\'s';
out = replace( str, /([^\s]*)/gi, replacer );
// returns 'Oranges And Lemons Say The Bells Of St. Clement\'s'
