<summary> About stdlib... </summary>

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

Replace search occurrences with a replacement string.

Installation

npm install @stdlib/string-base-replace

Usage

var replace = require( '@stdlib/string-base-replace' );

replace( str, search, newval )

Replaces search occurrences with a replacement string.

var out = replace( 'beep', /e/g, 'o' );
// returns 'boop'

If provided a function as the third argument, the function is invoked for each match, and the function's return value is used as the replacement string.

function replacer( match, p1 ) {
    return '/' + p1 + '/';
}
var str = 'Oranges and lemons';
var out = replace( str, /([^\s]+)/gi, replacer );
// returns '/Oranges/ /and/ /lemons/'

Notes

The function assumes that the search argument is a regular expression. Accordingly, the function should not be used as a general drop-in replacement for String.prototype.replace.

Examples

var capitalize = require( '@stdlib/string-base-capitalize' );
var replace = require( '@stdlib/string-base-replace' );

var 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'

Notice

This package is part of stdlib, a standard library for JavaScript and Node.js, with an emphasis on numerical and scientific computing. The library provides a collection of robust, high performance libraries for mathematics, statistics, streams, utilities, and more.
