Insert space before capital letters

Question

I have a string \"MySites\". I want to place a space between My and Sites.

How can I do this in jQuery or JavaScript?

Answer 1

You can use String#split() and a look-ahead for the capitalized alphabet ([A-Z]) and then Array#join() the array with a space:

let stringCamelCase = "MySites";

let string = stringCamelCase.split(/(?=[A-Z])/).join(" ");

console.log(string)

Or, as a String Object function:

String.prototype.cC2SC = function() {
  return this.split(/(?=[A-Z])/).join(" ");
}

console.log("MyCamelCase".cC2SC());
