get Array-Object-String thing from the given Object

Question

I have such an Object
freq = { a: 50, r: 25, m: 25 }

I want to convert it to this Array-Object like thing

Answer 1

Try this, I think it is the most performant way to do it, because .map() is slower than simple for loop:

let freq = { a: 50, r: 25, m: 25 } ;
let dps = [];

for (let prop in freq) {
    dps.push({
        label: prop,
        y: freq[prop]
    });
}

console.log(dps);
