Question

I am learning javascript and I am analyzing existing codes.

In my JS reference book, it says to search on a single space use “\s“?

But I have came across the code

obj.match(/Kobe Bryant/);

Instead of using \s, it uses the actual space?

Why doesn’t this generate an error?

Answer 1

The character class \s does not just contain the space character but also other Unicode white space characters. \s is equivalent to this character class:

[\t\n\v\f\r \u00a0\u2000\u2001\u2002\u2003\u2004\u2005\u2006\u2007\u2008\u2009\u200a\u200b\u2028\u2029\u3000]
