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

Using for loop and map

//Using for loop for object interation
const freq = { a: 50, r: 25, m: 25 };
var finalFreq=[];
for(let i in freq){
  finalFreq.push({label:i,y:freq[i]});
}
console.log(finalFreq);

//Using map and object keys
var finalFreq=Object.keys(freq).map((freqIndex)=>{
              return {label:freqIndex,y:freq[freqIndex]};
              });
console.log(finalFreq);
