## Built-in Objects in JavaScript 2023, Generate Random Number, Check if Number is Integer, Codecademy

In this Introduction to JavaScript Codecademy lesson, Built-in Objects, we take a look at some built-in objects and their useful functionality. We first learn that there is a Math object with many different methods we may use, and in this specific lesson, we learn about generating a random number using the Math.random() method. Using this will cause JS to generate a random number between 0 and 1. We are able to multiply this result by a number to generate a random number between 0 and the number multiplied. We then learn that we are able to round a number in Javascript using the .ceil() method which returns the smallest integer greater than or equal to a decimal number. After that we learn of a method on the Number object which allows us to check if a value is an integer or not. We learn this is possible through the JavaScript built-in Number object method, .isInteger() which allows us to pass in a value, and have it checked, as to whether or not it is an integer. This lesson begins to show us the different methods and objects that are available to us in the JavaScript language. Master and understand JavaScript built-in methods in 2023 and beyond to truly begin to master JavaScript and programming forever!
