Instead, it displays an error with the red color and sometimes it will appear with the “stack trace” but not this case (don’t worry much about it right now.) alert() Just like console.warn(), but it is not a warn anyone. Likewise, in your console type: console.error("This is not exactly an error, but I just did it for fun")

Now in your console type something similar to this: console.warn("Be careful") Īs the name of this, console.warn() method warns developers when they were trying to make a not wise decision and also plus a symbol and some yellow messages.

But for now, I will just list 2 other frequently used console which are console.warn and console.error(). Not only do we have console.log(), but we also have a lot of other console methods (A JavaScript method is a property containing a function definition – we’ll talk about property and function soon). You also can see the word undefined when you hit enter, it’s normal, don’t be freaking out. It can be a string, a number, a function or an object, etc…(don’t worry about that, we will talk about it soon).

Īs can be observed, the duty of console.log() is print out some outputs which is being wrapped in the parentheses to the console.

Ignore everything else at this time, focusing on the console tab: When you open up the console, you will see something like this. In order to open your browser’s console from Chrome, in Windows, open Chrome browser and type, ctrl+shift+i (On Mac is cmd+option+j). At first, IDEs are not necessary to run JavaScript files, you can write, run and debug your JavaScript on your own browser. JavaScript is the programming language that has been designed to run mainly on the web browser. Sounds confusing, but things will get more clear if you have time and play with it. Most of the time, you can just think of JavaScript as a dynamically typed language and it supports multiple paradigms, meaning you don’t need to specify a type when you declare variable, function, etc…Multiple paradigms meaning you can use this language to write OOP code, but also other paradigms such as POP (Procedural Oriented Programming), or FP (Functional Programming).

In technobabble, JavaScript often abbreviated as JS, is a high-level, interpreted programming language that conforms to the ECMAScript specification. We’ll cover from the very first steps with the easiest way to make things clear.įirst, let’s define what is JavaScript? Don’t confuse between Java and JavaScript, they are 2 completely different programming languages.
