How can I convert an Object to an Array of key-value pairs in JavaScript?

Answer 1

To convert an object to an array of key-value pairs in javascript, you can use Object.keys() and map() to do it. For example:

Var object={“1”:72,”2”:12,”3”:91};

Var result=Object.keys(object).map((key)=>[Number(key),object[key]);

console.log(result);
