In this post we will give you information about Fix object.forEach is not a function error in JavaScript. Hear we will give you detail about Fix object.forEach is not a function error in JavaScriptAnd how to use it also give you demo for it if it is necessary.
we are going to learn about how to Fix the object.forEach is not a function error in JavaScript
When we use a forEach() method on a value which is not an type array we will get the following error in our console.
Here is an example of using forEach on a object:
const user = { name: "john", place: "italy"};user.forEach(el=> console.log(el));// Uncaught user.forEach is not a functionTo fix the error, use the Object.keys() method to get the object keys in a array format and loop through it using forEach method.
Here is an example:
const user = { name: "john", place: "italy"};const keys = Object.keys(user);keys.forEach(key=> { console.log(user[key]); });or we can use the Object.values() method which is similar to Object.keys() but it returns the values in array format.
const user = { name: "john", place: "italy"};const values = Object.values(user);values.forEach(value=> { console.log(value); });We can also iterate through an object by using for..in loop.
const user = { name: "john", place: "italy"};for (let key in user){ console.log(user[key])}Output:
"john""italy"
