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

You could take the entries of the object and take a destructuring assignment for the key/value pairs and map new objects with short hand properties.

var freq = { a: 50, r: 25, m: 25 },
    dps = Object.entries(freq).map(([label, y]) => ({ label, y }));
    
console.log(dps);
