Javascript Enum To Corresponding String Value

Question

So I have this in the javascript for my page:

var TEST_ERROR  = {
        \'SUCCESS\'   :   0,
        \'FAIL\'      :   -1,
        \'ID_ERROR\'  :   -2
            


        

Answer 1

The best way to do it is:

export const UserLevel = Object.freeze({
   BABY: 1,
   CHILED: 2
});

Why we need to add freeze UserLevel is const but we can change the values inside, so freeze will make it safe for changes.
