Well i’m glad it helps a bit 
There is some other thing that is verry usefull i discoverd a while ago.
u are using array1,array2,array3 etc as variable names.
U can access them in a loop aswel like this
var array1 = “Something”
var array2 = “Some more things”
var array3 = “Alot of things”
for ( let i = 0 ; i < 3 ; i ++ ) {
console.log( eva l(“array” + i.toString())
}
//Something
//Some more things
//Alot of things
helped me alot in a program i once made years ago in another programming language.
kind regards,
Kristof.
