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, document 8000 ed, 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!
Reverse a string.
npm install @stdlib/string-reverseAlternatively,
- To load the package in a website via a
scripttag without installation and bundlers, use the ES Module available on theesmbranch. - If you are using Deno, visit the
denobranch. - For use in Observable, or in browser/node environments, use the Universal Module Definition (UMD) build available on the
umdbranch. - To use as a general utility for the command line, install the corresponding CLI package globally.
The branches.md file summarizes the available branches and displays a diagram illustrating their relationships.
var reverseString = require( '@stdlib/string-reverse' );Reverses a string.
var out = reverseString( 'last man standing' );
// returns 'gnidnats nam tsal'
out = reverseString( 'Hidden Treasures' );
// returns 'serusaerT neddiH'
out = reverseString( 'Lorem ipsum 𝌆 dolor sit ameͨ͆t.' );

npm install -g @stdlib/string-reverse-cliUsage: reverse [options] [<string>]
Options:
-h, --help Print this message.
-V, --version Print the package version.
--split sep Delimiter for stdin data. Default: '/\\r?\\n/'.
-
If the split separator is a regular expression, ensure that the
splitoption is either properly escaped or enclosed in quotes.# Not escaped... $ echo -n $'beep\nboop' | reverse --split /\r?\n/ # Escaped... $ echo -n $'beep\nboop' | reverse --split /\\r?\\n/
-
The implementation ignores trailing delimiters.
$ reverse foobar
raboofTo use as a standard stream,
$ echo -n 'foobar' | reverse
raboofBy default, when used as a standard stream, the implementation assumes newline-delimited data. To specify an alternative delimiter, set the split option.
$ echo -n 'foobar\tbaz' | reverse --split '\t'
raboof
zabThis 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.
