Is official solution for Computed Property correct?

[Bushwazi]

Terminal presents the following as the official solution:
console.log({
[+process.argv[2] % 2 === 0 ? "even" : "odd"]: +process.argv[2],
[+process.argv[2] + +process.argv[3]]: +process.argv[2] + +process.argv[3],
});

When is should be something like (but probably prettier):

var evenOrOdd = +process.argv[2];
var evenOrOddKey = evenOrOdd % 2 === 0 ? "even" : "odd";
var sum = +process.argv[3] + evenOrOdd;
var obj = {
[evenOrOddKey]: evenOrOdd,
[sum]: sum
};
console.log(obj);

Just passing by leaving my two cents: I think the purpose of this exercise is to use Computed Property at its most. The actual official solution is indeed a correct solution, and if you strictly follow the rule of not using temporary variables, its actually a great solution since it doesn't use the var keyword at all.
