Adding array elements to object's key and values

If i have the following array

const Array = ['Michael', 'student', 'John', 'cop', 'Julia', 'actress']

How could i make an object like

const Object = {
Michael: student,
John: cop, 
Julia: actress,
}

Is there a way to make the even index elements to be the object's keys and the odd index elements to be the key's values?

You could split the array into chunks of size 2 and then convert it to an object with Object.fromEntries.

let arr = ['Michael', 'student', 'John', 'cop', 'Julia', 'actress'];
let obj = Object.fromEntries([...Array(arr.length / 2)]
            .map((_, i)=>arr.slice(i * 2, i * 2 + 2)));
console.log(obj);

let arr = ['Michael', 'student', 'John', 'cop', 'Julia', 'actress'];

let obj={};

arr.forEach((element, index) => {

  if(index % 2 === 0){

    obj[element] = arr[index+1];

  }
})

console.log(obj);

A simple for loop that steps by two indexes at a time would work.

Try like below

const array = ['Michael', 'student', 'John', 'cop', 'Julia', 'actress'];

const output = {}

for(let i = 0; i < array.length; i+=2){
  output[array[i]] = array[i+1]
}

console.log(output);
