This is a function that checks if a given character is a white space character:
\s
, which equals all Unicode Space Separators (including [ \t\v\f]
), the BOM
(\uFEFF
), and line terminators ([\n\r\u2028\u2029]
).
Not often, as it’s relatively simple to do yourself. This package exists because it’s needed in several related packages, at which point it becomes useful to defer to one shared function.
This package is ESM only. In Node.js (version 14.14+, 16.0+), install with npm:
npm install is-whitespace-character
In Deno with esm.sh
:
import {isWhitespaceCharacter} from 'https://esm.sh/is-whitespace-character@2'
In browsers with esm.sh
:
<script type="module">
import {isWhitespaceCharacter} from 'https://esm.sh/is-whitespace-character@2?bundle'
</script>
import {isWhitespaceCharacter} from 'is-whitespace-character'
isWhitespaceCharacter(' ') // => true
isWhitespaceCharacter('\n') // => true
isWhitespaceCharacter('\uFEFF') // => true
isWhitespaceCharacter('_') // => false
isWhitespaceCharacter('a') // => false
isWhitespaceCharacter('💩') // => false
This package exports the identifier isWhitespaceCharacter
.
There is no default export.
Check if the given code point (number
), or the code point at the first index
(string
), is a whitespace character.
This package is fully typed with TypeScript. It exports no additional types.
This package is at least compatible with all maintained versions of Node.js. As of now, that is Node.js 14.14+ and 16.0+. It also works in Deno and modern browsers.
