You can use a for loop or the Array forEach() method to loop through JSON Array in JavaScript. In this tutorial, you will learn how to loop the array of JSON objects in JavaScript.
JavaScript loop through JSON Array examples
Simple example code Using a for loop. Use a for loop to iterate over each object in the array, and log the name and age properties to the console for each object.
javascriptCopy codeconst jsonArray = [
{ name: 'John', age: 28 },
{ name: 'Jane', age: 32 },
{ name: 'Bob', age: 45 }
];
for (let i = 0; i < jsonArray.length; i++) {
console.log(jsonArray[i].name, jsonArray[i].age);
}Using the Array.forEach() method:
The forEach() method to iterate over each object in the array, and log the name and age properties to the console for each object. Note that we use an arrow function to define the callback function for the forEach() method.

Hi Rohit,
Have you tried using the console.table(jsonArray)? Also, it is not really a JSON array, just a JS array.
