You can do it like this:

let url = "https://google.com";

let novaUrl = url.replace(/^https?:\/\//, '');

console.log(novaUrl);

A simple replace works.

You could also use a regex in replace to remove both "http://" and "https://".

let input = 'http://answall.com';
input = input.replace('http://', '');

console.log(input);

let input2 = 'https://answall.com';
input2 = input2.replace(/^https?:\/\//,'', '');

console.log(input2);

You can use index:

let uri = 'meusite.com'

// -1 é não encontrado
if (uri.indexOf('http://') == -1 && uri.indexOf('https://') == -1){
   uri = 'http://' + uri;
}

    I think this is the best answer not to insert http if the input already has. But I think you should check https also. +1
