I want to convert an object like this:
{"1":5,"2":7,"3":0,"4":0,"5":0,"6":0,"7":0,"8":0,"9":0,"10":0,"11":0,"12":0} into an array of key-value pairs like this:
[[1,5],[2,7],[3,0],[4,0]...]. How can I convert an Object to an Array of key-value pairs in JavaScript?

JavaScript Objects Convert object's values to array You can convert its values to an array by doing: var array = Object. keys(obj) . map(function(key) { return obj[key]; }); console.
So, what is the meaning of {} in JavaScript? In JavaScript, we use {} braces for creating an empty object. You can think of this as the basis for other object types. Object provides the last link in the prototype chain that can be used by all other objects, such as an Array.
const arr = [{id:1,name:"aa"},{id:2,name:"bb"},{id:3,name:"cc"}]; We are required to write a JavaScript function that takes in one such array and returns an object of the object where the key of each object should be the id property.
You can use Object.keys() and map() to do this
var obj = {"1":5,"2":7,"3":0,"4":0,"5":0,"6":0,"7":0,"8":0,"9":0,"10":0,"11":0,"12":0} var result = Object.keys(obj).map((key) => [Number(key), obj[key]]); console.log(result);If you love us? You can donate to us via Paypal or buy me a coffee so we can maintain and grow! Thank you!
