Syntax error Map multiple properties in array of objects to the same array JavaScript

Map multiple properties in array of objects to the same array JavaScript

Suppose, we have an array of objects like this −

const arr = [
   {a: 1, b: 2},
   {a: 3, b: 4},
   {a: 5, b: 6}
];

We are required to write a JavaScript function that takes in one such array of objects. The function should then map this array to an array of Number literals like this −

const output = [1, 2, 3, 4, 5, 6];

Example

const arr = [
   {a: 1, b: 2},
   {a: 3, b: 4},
   {a: 5, b: 6}
];
const pushToArray = (arr = []) => {
   const result = arr.reduce((acc, obj) => {
    acc.push(obj.a);
   acc.push(obj.b);
   return acc;
}, []);
   return result;
};
console.log(pushToArray(arr));

Output

And the output in the console will be −

[ 1, 2, 3, 4, 5, 6 ]
