JavaScript method to get unicode values of string

The snippet below is from a larger codeblock of a project, the job of the snippet is to get the unicode values of each character and it works fine execpt from numbers 1 - 9 ( 0 works too ) which return undefined.

const icons = '$677y8';
for(let i = 0; i < icons.length; i++){

console.log(icons.codePointAt(icons[i]));
}

Also, i tried charCodeAt() method it returns NaN

const icons = '$677y8';
for(let i = 0; i < icons.length; i++){

console.log(icons.charCodeAt(icons[i]));
}

Is there another standard JavaScript method to get this done?

You have invoked it wrong, it is String.prototype.codePointAt(position).

So you need to pass the i th index to the codePointAt function as the position of the string to look for the Unicode value:

const icons = '$677y8';
for (let i = 0; i < icons.length; i++) {
  console.log(icons.codePointAt(i));
}

btw, charCodeAt() is UTF-16, where as codePointAt() is Unicode.

//gets UTF-16 values
const icons = '$677y8';
for (let i = 0; i < icons.length; i++) {
  console.log(icons.charCodeAt(i));
}
