Omg!! This is so simple :) I can't believe I didn't get this idea by myself. Thanks

But if we put dots or something to assert, it returns true. =)

What do you mean? Can you show an example?

threeWords('word .,. word');

I see. You can change it <pre class='brush: javascript'>/[a-zA-Z]+\s[a-zA-Z]+\s[a-zA-Z]+/.test(data); </pre>

You can make it even smaller with the ignore case flag <pre class='brush: javascript'>/[a-z]+\s[a-z]+\s[a-z]+/i.test(data); </pre>

I found a different one: <pre class='brush: javascript'>\[^\d\W]+\b [^\d\W]+\b [^\d\W]+\g </pre> Matched anything not number or non-word character followed by a word boundary

This is not a valid solution. It incorrectly returns true for "!asd asd asd!" and "123asd asd asd123".

Description says: "You are given a string with words and numbers separated by whitespaces (one space)."

sterlinghurd1 on Aug. 25, 2016, 8:58 p.m.
You're right. I missed that.

Description says "The words contains only letters. You should check if the string contains three words in succession." so sterlinghurd1 is right. However your solution is actually simple and perfect

It's an amazing solution!

정규식 너무 사기같아 이사기꾼새끼야

So close: function threeWords(data) { return /[A-Za-z]+\s[A-Za-z]+\s[A-Za-z]+/.test(data); }
