How do I read an item of an object named by a variable?

Question

var myObj = {
    test: 0,
    other: 'none'
};
var readItem = 'test';
console.log(myObj.readItem);

How would I be able to hold, in a variable, the name of an item in an object and then use that variable to call the item? Thanks!

Answer 1

Can be looked up via the indexer:

myObj[readItem]

var myObj = {
    test: 0,
    other: 'none'
};
var readItem = 'test';
console.log(myObj[readItem]);

Answer 2

You can access the object property by following pattern

myObj[readItem];

var myObj = {
    test: 0,
    other: 'none'
};
var readItem = 'test';
console.log(myObj[readItem]);
