How can I iterate through keys and values in JavaScript

Question

With the help of code, can you tell me How I can iterate through keys and values in JavaScript?

Answer 1

In JavaScript , you can iterate through keys and values using these methods:

1.Using Object.keys()

const obj = { a: 1, b: 2, c: 3 };

Object.keys(obj).forEach(key => {

  console.log(key, obj[key]); // key and value

});

2. Using Object.entries()

const obj = { a: 1, b: 2, c: 3 };

for (let [key, value] of Object.entries(obj)) {

  console.log(key, value); // key and value

}
