How to get started with learning JavaScript

If you're new to programming, JavaScript is a great language to start with. It's relatively simple to learn, and there are a lot of tutorials and resources available online. In this blog post, we'll go over some of the different functions in JavaScript and how they can be used.

JavaScript has a number of built-in functions, which are methods that can be used on objects. For example, the Array object has a sort() method, which can be used to sort an array of data. The String object has a length property, which returns the number of characters in a string. And the Math object has methods like round() and ceil() for rounding numbers up or down.

There are also global functions in JavaScript, which are functions that are available anywhere in your code. These include things like isNaN() for checking if a value is not a number, and parseInt() for converting strings to integers.

Finally, there are also user-defined functions, which are functions that you create yourself. These can be used to group together a set of related code, or to perform some specific task. For example, you could create a function to calculate the average of an array of numbers
