Is there a way to assign a value of an object property as a key in the same object?
Like this:
var o = {}
o = {
a: 111,
b: 222,
[o.a]: 'Bingo'
};
This code is wrong because the result is
{a: 111, b: 222, undefined: 'Bingo'}
You have to do it in two steps
var o = {
a: 111,
b: 222
};
o[o.a] = 'Bingo';
console.log (o);Alternatively, store 111 in a variable first
var x = 111;
var o = {
a: x,
b: 222,
[x]: 'Bingo'
};
console.log (o);
