ERROR - "Object to Array"

// Noobs:

let number = {
    one: 1,
    two: 2,
};
let keys = [];
for (let numbers in number) {
    if (number.hasOwnProperty(numbers)) {
        keys.push(numbers);
    }
}

console.log(keys) // [ 'one', 'two' ]

// Pro:

let number = {
    one: 1,
    two: 2,
};
let key   = Object.keys(number) // [ 'one', 'two' ]
let value = Object.values(number) // [ 1, 2 ]
let entry = Object.entries(number) // [ [ 'one', 1 ], [ 'two', 2 ] ]

Everyone has their own perspective sir.

No he meant your had typos in your variable names. You declared a "number" variable but referenced "numbers" (with an s) in your code examples. The code literally doesn't run.

[Rahul]

Agreed.
