Get name of Variable a string in Javascript

lets say I have an array: it could look like this at one time:

var fruit = [apple,orange];

or like this:

var fruit = [orange, apple];

These are global variables, equaling some value - orange and apple How could I get the name of the variable at index 0 - (fruit[0]) of fruit as a string?

Thanks

Solution

  • To elaborate on @evolutionxbox comments – you'd need to use an object such as:

    const orange = 'An orange'
const apple = 'An apple'

const fruit = {
  orange,
  apple
}

console.log(Object.keys(fruit)) // [ 'orange', 'apple' ]
console.log(Object.keys(fruit)[0]) // 'orange'
console.log(fruit.apple) // 'An apple'
