Iterate through an array in javascript

Question

within the console.log I am receiving an array{items: Array(1)}

items: Array(1)
0: {id: 4, imageIndex: 3}
length: 1
__proto__: Array(0)
__proto__: Object

I am trying to print through this array to retrieve the imageIndex and getting an undefined.

for (var image in imageList) {
    console.log(image.imageIndex);
}

If I use for...of within the loop, I get an 'imageList' is not iterable.

IF you use for in , it gives you the index, then you might have to access it as item[i].imageIndex — Geeky, Nov 17 '18 at 01:16

Try for of

check this snippet

const arr =[{id: 4, imageIndex: 3}]
for (var item of arr) {
console.log(item.imageIndex);
}

imageList is not iterable is the error I receive when I use of instead – drai29 Nov 17 '18 at 01:34
