If you follow strict criteria, the function returns the number but not boolean type. Of course, you can say that zero and one are implicitly convertible to boolean :)

Therefore I don't write in TypeScript.

is there a shorter one? <pre class='brush: javascript'>var isEven = x => x<(x^1) var isEven = x => !(x&1) var isEven = x => x&1^1 </pre>
