How do I access the Object.prototype method in the following logic?

Question

I am using the following logic to get the i18n string of the given key.

export function i18n(key) {
  if (entries.hasOwnProperty(key)) {
    return entries[k         


        

Answer 1

It seems like this would also work:

key in entries

since that will return a boolean on whether or not the key exists inside the object?
