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 the substring after the last occurrence of a specified search string.
bash
npm install @stdlib/string-base-replace-after-last
javascript
var replaceAfterLast = require( '@stdlib/string-base-replace-after-last' );
#### replaceAfterLast( str, search, replacement, fromIndex )
Replaces the substring after the last occurrence of a specified search string.
javascript
var str = 'beep boop';
var out = replaceAfterLast( str, ' ', 'loop', str.length );
// returns 'beep loop'
out = replaceAfterLast( str, 'o', 'bar', str.length );
// returns 'beep boobar'
To begin searching from a specific index, provide a corresponding fromIndex argument.
javascript
var out = replaceAfterLast( 'beep boop beep', ' ', 'loop', 6 );
// returns 'beep loop'
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.
javascript
var out = replaceAfterLast( 'beep boop beep', ' ', 'loop', -1 );
// returns 'beep boop loop'
fromIndex resolves to an index which is less than 0, the function returns the provided string unchanged.
javascript
var replaceAfterLast = require( '@stdlib/string-base-replace-after-last' );
var str = 'beep boop';
var out = replaceAfterLast( str, 'p', 'see', str.length );
// returns 'beep boopsee'
str = 'Hello World!';
out = replaceAfterLast( str, 'xyz', 'foo', str.length );
// returns 'Hello World!'
str = 'Hello World!';
out = replaceAfterLast( str, '', 'foo', str.length );
// returns 'Hello World!'
str = '';
out = replaceAfterLast( str, 'xyz', 'foo', str.length );
// returns ''
str = 'beep boop beep baz';
out = replaceAfterLast( str, 'beep', 'foo', 5 );
// return 'beepfoo'
