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!

rescape

Escape a regular expression string or pattern.

Installation

1npm install @stdlib/utils-escape-regexp-string

Usage

1var rescape = require( '@stdlib/utils-escape-regexp-string' );

rescape( str )

Escapes a regular expression string or pattern.

1var str = rescape( '/[A-Z]*/' );
2// returns '/\\[A\\-Z\\]\\*/'
3
4str = rescape( '[A-Z]*' );
5// returns '\\[A\\-Z\\]\\*'

If provided a value which is not a primitive string, the function throws a TypeError.

1try {
2    rescape( null );
3    // throws an error...
4} catch ( err ) {
5    console.error( err );
6}

The following characters have special meaning inside of regular expressions and need to be escaped in case the characters should be treated literally:

description value
Backslash \
Braces { }
Brackets [ ]
Caret ^
Dollar Sign $
Forward Slash /
Asterisk *
Parentheses ( )
Period .
Plus Sign +
Vertical Bar |
Question Mark ?
