Lastly, before we look at today’s itinerary, remember that JavaScript, just like HTML and CSS (but maybe even more so), is a vast language.

JavaScript is also a fun and rewarding language, which is especially important when you’re just getting started in software development. So, in that sense, it’s more accessible than some other languages like C and Java. When we say ‘easier’, we mean in terms of how quickly you can go from being a JavaScript novice to someone who can actually make a living writing professional, high quality JavaScript code. For starters, compared to other languages like C and Java, JavaScript is generally easier to learn. In short, it is everywhere-and for good reasons. It can also help create solid backends with platforms like Nodejs, runs desktop applications like Slack, Atom, and Spotify, and runs on mobile phones as Progressive Web Apps (PWAs). It is the foundation of frontend web development and is the key ingredient in frameworks like ReactJS, Angular, and VueJS. JavaScript, as you might know, is ubiquitous in today’s software development world. Welcome to the fifth and final day of your web development short course!

This is the simplest JavaScript code, which shows the demo of how the simplest JavaScript code is created in each and every article for beginner learners.💬 “In some ways, programming is like painting.
Note: I'm using the "document.write()" method only for the example purpose, but you can choose the console.log() method to see the "num is not less than 10" to the document.ĭue to the fact that "num" in this example has a value of 12, which is greater than 10, the "else" block will be executed, and the program's output will read The program will run the statement contained in the "else" block if the value of "num" is greater than 10, in which case it will use the "document.write()" method to write Method, if the value of "num" is less than 10. The program will run the statement inside the "if" block, which in this case is to write "num is less than 10" to the document using the document.write() Than 10 or not using an if-else statement. It then checks to see if the value of the variable "num" is less The provided code creates a "num" variable and gives it the value of 12. Document.write(num + " is less than 10") Įlse document.write(num + " is not less than 10")
