How to turn a JSON object into a JavaScript array in JavaScript ?
Suppose, we have this JSON object where index keys are mapped to some literals −
const obj = {
"0": "Rakesh",
"1": "Dinesh",
"2": "Mohit",
"3": "Rajan",
"4": "Ashish"
};We are required to write a JavaScript function that takes in one such object and uses the object values to construct an array of literals.
Example
The code for this will be −
const obj = {
"0": "Rakesh",
"1": "Dinesh",
"2": "Mohit",
"3": "Rajan",
"4": "Ashish"
};
const objectToArray = (obj) => {
const res = [];
const keys = Object.keys(obj);
keys.forEach(el => {
res[+el] = obj[el];
});
return res;
};
console.log(objectToArray(obj));Output
And the output in the console will be −
[ 'Rakesh', 'Dinesh', 'Mohit', 'Rajan', 'Ashish' ]
