Argument of Different Data-Types

Is it a good idea / practice to do the following:

export const checkAndUpdateCredit = ( total, addback = false ) => {
 // here, addback can be an obj or boolean
 let value = total - addback.value
};

As per the comment, if the argument of addback isn't passed, it defaults to false, else an object is required to be passed. Here a single parameter can be either an object or a boolean. Is this a good practice / acceptable?

Solution

  • You could use a default value inside of addback

    export const checkAndUpdateCredit = (total, addback = { value: 0 }) => {
//                                                    ^^^^^^^^^^^^
