About
This dependency checks if a given string only contains whitespace characters.
This can be done natively with the String.prototype.trim method.
Usage
" ".trim().length === 0; // true
"\n\t".trim().length === 0; // true
"\r\n".trim().length === 0; // true
"\t".trim().length === 0; // true
"foo".trim().length === 0; // false
or in a function:
function isWhitespace(str) {
return str.trim().length === 0;
}
isWhitespace(" "); // true
isWhitespace("\n\t"); // true
isWhitespace("\r\n"); // true
isWhitespace("\t"); // true
isWhitespace("foo"); // false
