Note that variables are case sensitive. That means lastname and lastName will be handled as two different variables. They are variables which can have their own values and methods. The latter are actions that you can perform on objects. Next up in our JavaScript cheat sheet are arrays. Arrays are part of many different programming languages. They are a way of organizing variables and properties into groups. If you have variables, you can use them to perform different kinds of operations.

To do so, you need operators. JavaScript functions are blocks of code which perform a certain task.

A basic function looks like this:. As you can see, it consists the function keyword plus a name. You can create your own, but to make your life easier — there are also a number of default functions. A common application for functions is the output of data. For the output, you have the following options:. Loops are part of most programming languages.

They allow you to execute blocks of code desired number of times with different values:. These types of statements are easy to understand. Using them, you can set conditions for when your code is executed.

If certain conditions apply, something is done, if not — something else is executed.

In JavaScript, strings are marked with single or double quotes. If you want to use quotation marks in a string, you need to use special characters:. Regular expressions are search patterns used to match character combinations in strings. The search pattern can be used for text search and text replace operations.

You can also work with and modify dates and time with JavaScript. This is the next chapter in the JavaScript cheat sheet. It is the code of the structure of a webpage. Besides HTML elements, JavaScript is also able to take into account the user browser and incorporate its properties into the code. Events are things that can happen to HTML elements and are performed by the user.

The programming language can listen for these events and trigger actions in the code. No JavaScript cheat sheet would be complete without them. When working with JavaScript, different errors can occur. There are several ways of handling them:. JavaScript is gaining much importance as a programming language. It is increasingly the go-to language for building web properties thanks to its proven track record and benefits.


In the JavaScript cheat sheet above, we have compiled many of the most basic and important operators, functions, principles, and methods.
