Setting & Deleting Properties

This lesson will teach you how to set properties using dot operators or square brackets, and how to delete properties.

Setting Values Using Dot Notation

A property being accessed by the dot operator can be set/updated using the assignment operator (=).

Example

Javascript (babel-node)
//creating an object named employee
var employee = {
//defining properties of the object
//setting data values
name : 'Joe',
age : 20
}
console.log("Originally age was:",employee.age)
//updating the value of "age"
employee.age = 24
console.log("New age is:",employee.age)
