What makes javascript unique

In the previous example, what would happen if your oven timer goes off indicating that things are finished in the oven, but someone else comes home with the ingredients for a peanut butter and jelly sandwich at the same time? Returning to the analogy, as a person, you can only do one thing at a time. Should you sandwich or should you oven? The event queue is just a fancy way to explain that things should happen in the order they happen, which is a pretty logical approach.

So, if the alarm went off first, finish dealing with the oven before making the sandwich. But if someone came back from the store with the peanut butter and jelly ingredients before the alarm went off, make the sandwich first.

JavaScript is a funky programming language. Once you get a feel for it though, it becomes more and more intuitive. While foreign and strange at first, JavaScript solves problems in a truly elegant, intelligent, and even logical way. The very thing that makes JavaScript weird is the same thing that makes it powerful.

It can feel uncomfortable to write JavaScript at first. But the more you use it, the more it becomes second nature. Thank you so much for posting! I guess I can consider myself one of the lucky ones, as I took a deep dive of JavaScript first, before learning any other programming language, so I am actually more comfortable with it.

Thanks again and look forward to the next post! Your email address will not be published. Skip to content Industry Knowledge 6 min read. Ken Mazaika. What is JavaScript? Let me get into that a little deeper. How can this be? None of this makes sense!? JavaScript programming is different. Read it and this will start to make more sense. This is absolutely spot on. What are some common programming situations in which you need Javascript to take this approach?

Instead, you would: Reach out to the database Move onto the next step When the database comes back with the data, it would ping your code and you could do whatever you need to with the data.

Press Enter. But Javascript has both undefined and null 3. Tripe equals operator Why Javascript has tripe equals operator to compare equality? Callback functions Functions are first-class objects in Javascript, we can pass a function as an argument in another function and later execute that passed-in function or even return it to be executed later.

It begins in the year at the Netscape headquarters, where young Brendan Eich goes into a ten day sprint of coding and comes out on the other side with a new language.

As more people used browsers to use and experience the internet, there was a need for a programming language that would give life to the browser. It changed the way we thought about the internet and ushered a new era of browser based applications. Unlike many other languages, where you need to go download the language in your machine in order to access all of its features and create a development environment, with JavaScript anyone with a web browser suddenly has a development environment right in front of them.

Every browser supports JavaScript! You can simply open your browser, like Chrome , and navigate to Developer Tools , and start coding away! You can also use an Integrated development environment IDE or code editor like Visual Studio Code where you can create a file with the file extension. Visual Studio Code VS Code is more widely used to write code but there are other editors like Atom and Sublime Text which are quite common amongst developers.

Event-based programming One of the most impressive features of JavaScript is that it includes event-based programming. For instance, when you click the night-mode toggle, that is an event which triggers a JavaScript code segment that changes the CSS across the whole website from light colors to dark colors. JavaScript can be used to generate dynamic contents on a website as well.

Different HTML tags can be generated based on user input.
