Convert Array of Objects to Array of Arrays in JavaScript

Suppose, we have an array of objects like this −

const arr = [    {"Date":"2014","Amount1":90,"Amount2":800},    {"Date":"2015","Amount1":110,"Amount2":300},    {"Date":"2016","Amount1":3000,"Amount2":500} ];

We are required to write a JavaScript function that takes in one such array and maps this array to another array that contains arrays instead of objects.

Therefore, the final array should look like this −

const output = [    ['2014', 90, 800],    ['2015', 110, 300],    ['2016', 3000, 500] ];

Example

The code for this will be −

const arr = [    {"Date":"2014","Amount1":90,"Amount2":800},    {"Date":"2015","Amount1":110,"Amount2":300},    {"Date":"2016","Amount1":3000,"Amount2":500} ]; const arrify = (arr = []) => {    const res = [];    const { length: l } = arr;    for(let i = 0; i < l; i++){       const obj = arr[i];       const subArr = Object.values(obj);       res.push(subArr);    };    return res; }; console.log(arrify(arr));

Output

And the output in the console will be −

[ [ '2014', 90, 800 ], [ '2015', 110, 300 ], [ '2016', 3000, 500 ] ]
