Accesing Property of object using a variable

Question

Im trying to access a property of an object using using a variable which could change

var i = '16';

var object = {
        "15" : [ 3, 4, 5, 6 ],
        "16" : [ 1, 3 ],
        "17" : [ 1, 3, 4, 5, 6 ],
        "18" : [ 1, 3, 4 ]
}
console.log( object['i'] )

using the variable gives undefined however using

console.log( object['16'] )

gives you the array of that propery.

Does anyone know how i could work around this

`'i'` is a string not the variable `i` – Andreas Jan 25 '18 at 16:26 — Andreas, Jan 25 '18 at 16:26

Just remove quotes around your variable

var i = '16';

var object = {
        "15" : [ 3, 4, 5, 6 ],
        "16" : [ 1, 3 ],
        "17" : [ 1, 3, 4, 5, 6 ],
        "18" : [ 1, 3, 4 ]
}
console.log( object[i] )
