How to convert non numeric string to int

Question

For an assignment, i am trying to recreate a small project I once made in ASP.NET.

It converted each letter of a text to its int value, then added 1 en reconverted it to a char and put them all back into a single string.

Now I am trying to do this in Angular, but I am having trouble converting my non-numeric strings to its int value.

I tried it with ParseInt(), but this only seems to work if the string is a valid integer.

Is there any way to parse or convert non-numeric strings to an int value and how?

it seems like you will have to do the same thing you have done in your ASP.NET program; break your string into an array of char, then loop through the array and use char.charCodeAt() on each letter. — Claies

@Claies In ASP.NET I was simply doing (int)stringmsg[i] in a for loop, but the charCodeAt put me on the right track, so thank you. — Vahx

'String here'.split('').map(function (char) {
    return String.fromCharCode(char.charCodeAt(0) + 1);
}).join('');

If you mean char code.

This is probably good for Javascript, but i'm looking for an Angular/Typescript syntax solution. Perhaps the javascript tag should be removed from the question.. But this and @Claies comment helped me

Thankx to the helpful insights of Claies and Damien Czapiewski I constructed the following solution.

Loop through each character in my string in a for loop.
Then, for each char I retrieved its value with charCodeAt()
And to return to a string value I used fromCharCode()

encode(msg:string):string {

    let result: string = "";

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

            let msgToInt = msg.charCodeAt(i);

           // do stuff here

            result += String.fromCharCode(msgToInt);
        }
    }

    return result;
}
