How To Push JSON Object Into An Array Using JavaScript

You’ll learn how to push JSON object into an array using JavaScript. You can make use of Array.push method to push a JSON object to an array list.

let list = [];
let myJson = {
  "name" : "sam"
}
list.push(myJson);
console.log(list)

Let’s look at another use case where you have to create a JSON object dynamically from an array and push to another array.

let list = [];
let input = ["John","Hari","James"]
let myJson;


for(let i = 0; i < input.length; i++){
  myJson = {"name" : input[i]};
  list.push(myJson);
}

console.log(list)

Now instead of using a for loop you can also use JavaScript reduce method to create a new JSON object array dynamically.

let list = [];
let input = ["John","Hari","James"]
let myJson;

list = input.reduce((accumulator, currentValue, index, array) => {
  accumulator.push({"name" : currentValue});
  return accumulator;
},[])

console.log(list)
