How to remove numbers from array using regex in javascript

Question

I am not sure if this is right? I want to remove numbers from array(docs).

for (var i = 0; i < clean.length; i++) {

    var regex = /([^0-9]*)$/;

    console.log(regex.test(clean));

    tags.push(clean);

    if (regex.test(clean[i])) {

        clean.splice(i, 1);

    }
}

That's an object, are you sure you're working with an array here? — Adam Azad

Please update the source code in your question that will give myself and others something to work with rather than parts of it. Without having the complete source we can only make assumptions which don't always lead to a solid/correct answer, reproducing the problem will get you the help you want. — NewToJS

Assuming that clean an array. You can do use Array#filter to check if current element is an array.

var clean = ["0", "1", "a", "c", "3"],
    tags = [];
clean = clean.filter(function(v){

   return ! ( /[0-9]/g ).test(v);

});

tags = tags.concat(clean);

console.log( tags );

Very and simple! if you don't want to use return you could replace that line with if(!( /[0-9]/g ).test(v)){tag.push(v);} but still +1 for simplicity.
