So I've only used standard variable types in comparison functions (ints, floats, bools, strings, etc) - and this was my first time using code that looked like: fruit[i] === "🍎"
I first tried with a for loop like this:
for(fr in fruit) - and tried to compare fr to "🍎" - this didn't work
but for(i=0;i<fruit.length;i++) and fruit[i] === "🍎" worked.
Anyone able to help me understand why one type of for loop works and the other doesn't?
And how is the emoji actually being parsed?

A for..in loop on an array will iterate the indexes of the array, not the elements. If you want to iterate the array elements, you'd want to use a for..of loop. Also, emojis are character sequences, so they are effectively the string type in JavaScript.

We have so many loop types. if all you are doing is finding a specfic fruit a loop is not required. You can use indexOf property of the array or includes.
const fruit = ['🍎']; console.log(fruit.indexOf('🍎')) console.log(fruit.includes('🍎'))

like @inner fjord mentioned they are still strings starting with : and ending with : . these can be removed from the string and your apple will just say apple.
Strings them self's are encoded into a human readable format. Most websites/text editors use UTF-8 format https://en.wikipedia.org/wiki/UTF-8
Javascript can also decode & encode binary strings (1s and 0s) into human readable formats.
