Merging deep objects

The following code shows how to merge objects without losing values that are not defined in objects to merge.

import deepExtend from "@jalik/deep-extend";

const defaultColors = {
    cold: {
        blue: "#0000FF",
        green: "#00FF00"
    },
    hot: {
        red: "#FF0000",
        yellow: "#FFFF00"
    }
};

const customColors = {
    cold: {
        blue: "#48C2ED"
    },
    hot: {
        yellow: "#E6CB5F"
    }
};

// Merge all colors into a new object.
// The final colors will have custom blue and yellow colors,
// but the other colors will be the default ones.
const finalColors = deepExtend({}, defaultColors, customColors);
