@stdlib/string-base-replace-after

About stdlib...

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!

replaceAfter

Replace the substring after the first occurrence of a specified search string.

Installation

npm install @stdlib/string-base-replace-after

Usage

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

replaceAfter( str, search, replacement, fromIndex )

Replaces the substring after the first occurrence of a specified search string.

var out = replaceAfter( 'beep boop', ' ', 'loop', 0 );
// returns 'beep loop'

out = replaceAfter( 'beep boop', 'o', 'bar', 0 );
// returns 'beep bobar'

To begin searching from a specific index, provide a corresponding fromIndex argument.

var out = replaceAfter( 'beep boop beep baz', 'beep', 'foo', 5 );
// return 'beep boop beepfoo'

If fromIndex is less than zero, the starting index is resolved relative to the last string character, with the last string character corresponding to fromIndex = -1.

var out = replaceAfter( 'beep boop beep', ' ', 'loop', -6 );
// returns 'beep boop loop'

Notes

• If a search string is not present in a provided string, the function returns the provided string unchanged.
• If a search string is an empty string, the function returns the provided string unchanged.
• If fromIndex resolves to an index which is greater than or equal to str.length, the function returns the provided string unchanged.

Examples

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

var out = replaceAfter( 'beep boop', 'p', 'see', 0 );
// returns 'beepsee'

out = replaceAfter( 'Hello World!', 'xyz', 'foo', 0 );
// returns 'Hello World!'

out = replaceAfter( 'Hello World!', '', 'foo', 0 );
// returns 'Hello World!'

out = replaceAfter( '', 'xyz', 'foo', 0 );
// returns ''

out = replaceAfter( 'beep boop beep baz', 'beep', 'foo', 5 );
// return 'beep boop beepfoo'
