What’s JavaScript(JS)
JavaScript (JS) is a popular programming language that is widely used for web development, server-side programming, and creating desktop and mobile apps. Here’s a basic example of how to write a simple program in JavaScript:
This code first declares a variable called “message” and assigns it the string “Hello, World!” Then, it uses the console.log()
function to print the value of the variable to the console.
The code also includes an example of a function called “printMessage” that takes in a single argument “msg” and prints it to the console using console.log()
.
Then, there’s an example of a conditional statement that checks if a variable x
is greater than 0, and prints a message to the console depending on the result.
Lastly, the code includes an example of a for
loop that iterates 5 times, printing the current value of the variable i
to the console on each iteration.
These are just a few examples of the many things you can do with JavaScript. There are also many libraries and frameworks available, such as AngularJS, ReactJS, and VueJS, that can help you to build more complex and powerful web applications.
It’s important to keep in mind that in order to run JavaScript code in a web browser, it must be included in an HTML file and the file must be loaded into the browser.
JavaScript is a vast and complex language and this is just the tip of the iceberg, but I hope it helps you to understand the basics.
