remove specific characters using js regex

Question

My question is how to make the three steps I use into one step; how do I combine these to just one?

Thank you!

var string = "1.4 Whatever";
var a = string.replace(/[0-9]/g,'');
var b = a.replace(/[\.]/g, '');
var c = b.replace(/ /g, '');

console.log(c);

Just like this

var string = "1.4 Whatever";
var a = string.replace(/[0-9\. ]/g,'');

console.log(a);
