var string = '1234'
var check = Number(string);

console.log(check);

but if i give my string like below, it wont convert correctly.

var string = '1,234'
var check = Number(string);

console.log(check);

Is there any alternate available?

Answer 1

You have to remove all the non numeric characters from string for this to work.

var string = '1,234'

var check = Number(string.replace(',',''));

console.log(check);
