Can I turn the following into Ternary Operator? If so how? if (i === character.length - 1) { info += `and ${characters[i]}, `; } else { info += `${characters[i]}, `; }

const colours = ["red", "Orange", "Blue", "Pink", "black"] for (let i = 0; i < colours.length; i++) { console.log(`${colours[i]} is my fav colour`); } //Output:- // red is my fav colour // Orange is my fav colour // Blue is my fav colour // Pink is my fav colour // black is my fav colour

If I'm correct; here is my understanding of it. You know, since the array is four based on the number of items stored in CHARACTERS. Meaning, characters.length = 4 since that's the length of the array if we are to check it. Hence, character.length - 1 = 3, just like saying 4 - 1 = 3. Hope you understand.

Also, I guess what he meant in that if statement is that; if i = 3 OR i === characters.length - 1 also know as I === 4 - 1 which is = 3. We should loops around that or iterate(i++), iterate or gives us Sonic, Tails and Mario then append them to info += ` and ${characters[i], in this place. characters [i] which is equal to 3 based on characters.length -1 (or 4-1) is Luigi. That's how I guess he did. Not sure tho. I hope he sees this or anybody and correct if I'm wrong. Thanks!

The answer you're looking for lies in the index start value. First value of every array index is defined as 0(zero), so an array of four values would be indexed as 0, 1, 2, 3. Example; let names = ['Mike', 'Brad', 'John', 'Stupid Trump']; Total length of this array would be 4 as there are 4 values(names) in it but as every array index start from 0, Mike would be indexed as 0 and Trump would be indexed as 3. So when you say ".length -1", you are basically saying it to stop when the index value comes to 3 (4-1 or 'array length -1) which is equal to the last value of the index (3) which is Trump in this example case. Hope this helps!
