I am trying to use a key (unique number) and add a letter to that key (cause you cant just do var 230 = []). so I can push the right value to the right array. How can I do that??? ):
const keys = [230, 330]
let a230 = []
let a330 = []
keys.forEach((key, value) => {
a[key].push(value) //push value to a230...
}
)
