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!
Test whether a string contains only white space characters.
import isWhitespace from 'https://cdn.jsdelivr.net/gh/stdlib-js/assert-is-whitespace@esm/index.mjs';
Tests whether a string contains only white space characters.
var bool = isWhitespace( ' ' );
// returns true
- A white space character is defined as one of the 25 characters defined as a white space ("WSpace=Y","WS") character in the Unicode 9.0 character database, as well as one related white space character without the Unicode character property "WSpace=Y" (zero width non-breaking space which was deprecated as of Unicode 3.2).
- For non-string values, the function returns
false
.
