javascript - Why is this js function returning undefined?

Question

I'm writing a basic JS program to convert text into color to render in the DOM, and for some reason I just can't figure out how to get this function to return my intended array. Instead it just returns undefined and its driving me crazy.

In this function I have a few variables that need to be described. The "array" in question is a sample text. The "colorObject" is a object that pairs all of the characters with random hexadecimal colors, with the keys stored as strings and the values the random color, ie. a: "#D65522".

function letterToColor(array) {
    let colorArray = [];
    array.forEach(char => {
        colorArray.push(colorObject[char])
    });
    return colorArray;
};
