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!
Return a string created by joining array elements using a specified separator.
To use in Observable,
join = require( 'https://cdn.jsdelivr.net/gh/stdlib-js/array-base-join@umd/browser.js' )The previous example will load the latest bundled code from the umd branch. Alternatively, you may load a specific version by loading the file from one of the tagged bundles. For example,
join = require( 'https://cdn.jsdelivr.net/gh/stdlib-js/[email protected]/browser.js' )To vendor stdlib functionality and avoid installing dependency trees for Node.js, you can use the UMD server build:
var join = require( 'path/to/vendor/umd/array-base-join/index.js' )To include the bundle in a webpage,
<script type="text/javascript" src="https://cdn.jsdelivr.net/gh/stdlib-js/array-base-join@umd/browser.js"></script>If no recognized module system is present, access bundle contents via the global scope:
<script type="text/javascript">
(function () {
window.join;
})();
</script>Returns a string created by joining array elements using a specified separator.
var x = [ 1, 2, 3, 4, 5, 6 ];
var out = join( x, ',' );
// returns '1,2,3,4,5,6'-
If provided an array-like object having a
joinmethod, the function defers execution to that method and assumes that the method API has the following signature:x.join( separator ) -
If provided an array-like object without a
joinmethod, the function manually constructs the output string. -
If an array element is either
nullorundefined, the function will serialize the element as an empty string.
