JavaScript is a well-known programming language among the developers that helps them in producing powerful and interactive UIs for websites and applications. It very often known as the back-bone of the field of website development. By learning this language, you can assure a stable career for yourself. The very step you can take in this direction is understanding its most common features and learning them under JavaScript course.
So, let’s take a closer look at them once.
Common topics to learn in JavaScript
Variables: You must start from variables as they help developers in storing data inside JS. The stored date can be of many types including numbers, Boolean values or strings.
Functions: In programming languages like JS, we use functions to perform certain tasks. They are like condition and action based blocks of code that return outputs on getting inputs.
Conditional statements: JavaScript includes conditional statements such as if/else and switch/case, which allow for the execution of different blocks of code based on certain conditions.
Loops: JavaScript includes different types of loops such as for, while, and do/while loops, which allow for the repeated execution of code until certain conditions are met.
Objects: When developers talk about fundamental concept in JavaScript then it means they are talking about Objects mainly which help them working with real-world entities. Objects can contain properties and methods that define their behavior.
Arrays: The concept of Arrays comes in many applications as well. Same goes for array of JS. Arrays can work with multiple objects and help in storing a collection of elements.
Events: You can add the events functionality on your webpage with the help of events of JavaScript. Event listeners can be added to elements on a webpage to trigger specific actions when an event occurs.
DOM manipulation: DOM goes for Document Object Model here and is basically a programming interface. It allows JavaScript to work with the elements of HTML and CSS. JavaScript can be used to dynamically update and modify the contents of a webpage.
Asynchronous programming: The method of synchronous programming in JavaScript lets website developers to execute some code while waiting for the server requests to complete. This is achieved using callbacks, promises, and async/await functions.
Error handling: JavaScript includes error handling mechanisms such as try/catch statements, which allow for the handling of errors and exceptions that may occur during program execution.
Got an idea about the content, now it’s time to get started with the JavaScript course. You can also check the list of other similar programs under web development courses as well as web design courses offered at ADMEC.
