Why doesn't this give me the object I expected .. which is {1:2} Instead the console gives {a:2}

Question

function createObject (a, b) {
    const myObject = {a:b}
    console.log(myObject);
}

createObject(1, 2);

Should be `{[a]: b}` since you want to evaluate `a` as an expression rather than an identifier/key — Paul, Aug 13 '20 at 15:03

Without brackets, the property name of a literal object is not evaluated as an expression:

function createObject (a, b) {
    const myObject = {[a]: b}
    console.log(myObject);
}

createObject(1, 2);
