You can iterate over a JSON array and retrieve values using the following method:

  1. Using a for loop in JavaScript:
const jsonArray = [{"name": "Alice", "age": 30}, {"name": "Bob", "age": 25}];
for (let i = 0; i < jsonArray.length; i++) {
    console.log(jsonArray[i].name);
    console.log(jsonArray[i].age);
}
  1. Use the forEach method in JavaScript:
const jsonArray = [{"name": "Alice", "age": 30}, {"name": "Bob", "age": 25}];
jsonArray.forEach(item => {
    console.log(item.name);
    console.log(item.age);
});
  1. Use the for…of loop in ES6:
const jsonArray = [{"name": "Alice", "age": 30}, {"name": "Bob", "age": 25}];
for (const item of jsonArray) {
    console.log(item.name);
    console.log(item.age);
}

These methods can be used to loop through a JSON array and extract the desired values.
