Check if a character is a whitespace character: \s, which equals all Unicode Space Separators (including [ \t\v\f]), the BOM (\uFEFF), and line terminator ([\n\r\u2028\u2029]).
npm:
npm install is-whitespace-character
var whitespace = require('is-whitespace-character') whitespace(' ') // => true whitespace('\n') // => true whitespace('\uFEFF') // => true whitespace('_') // => false whitespace('a') // => true whitespace('💩') // => false
whitespaceCharacter(character|code)Check whether the given character code (number), or the character code at the first position (string), is a whitespace character.
