The process that front end developers use to construct websites has seen tremendous evolution during the past two decades. In order to convey how the languages interact with one another, Mozilla employs the striking image of a three-layered cake. JavaScript is located on top, followed by Cascading Style Sheets (CSS), and finally HTML.
The limitation of HTML at the time to manage design or style posed challenges for early front-end developers who used the language. The structure of a website as well as the fundamental components that comprise its appearance are both defined by HTML. The usage of HTML allows for characters to be made to seem bold or italicised, as well as for determining whether blocks of text should be paragraphs.
That's great if you want a website that's built only on text, but what if you want to alter the colour of the background? This is when cascading style sheets come into play. The language known as Cascading Style Sheets (CSS) is utilised in order to determine how a website should seem to the end user. Front End developers may avoid having to repeatedly type in a command every time they want to add a little style to their website by using CSS to code all of the stylistic changes in a single location. To illustrate, changing the colour of all of our headlines to blue requires only a few lines of CSS.
JavaScript is the icing on the cake, and it is responsible for transforming a static website into an interactive environment. If you were around in the middle of the 1990s and had the chance to explore the World Wide Web (think AOL CDs and dial-up connections), then you are well aware of the frustration that can be created by having to wait for a page to load. If you wanted to change anything on a website, you had to wait until it refreshed before you could do so. Thank goodness, our time spent waiting is now over. JavaScript is responsible for it.
Developers working on the Front End no longer have to wait for a website to load before they may change its parts (Imagine waiting for Twitter to refresh every time you update your feed.) Front End frameworks are another tool that developers utilise to improve or streamline JavaScript-based processes. For example, the AngularJS framework makes it possible for developers to quickly create single-page web applications. jQuery makes chores easier, and AJAX enables webpages to be updated without requiring the user to refresh the page by adding the markup language XML to JavaScript.
These languages are often seen towards the top of any listing of popular programming languages since they are used so frequently. According to the responses of developers to a poll conducted by WP Engine, HTML and JavaScript are also among the simplest languages to comprehend. It is generally agreed upon that JavaScript is a more versatile programming language than HTML, and that developers believe JavaScript to be the most innovative of all programming languages.
Key takeaway → Markup languages such as HTML, CSS, and JavaScript are the core building elements that go into Front End development. Learning any of these three languages does not require an excessive amount of time or effort and opens up a wide range of possibilities for creative expression and adaptability. In addition to being knowledgeable in the JavaScript frameworks, you will need to become fluent in these three programming languages if you want to work as a Front End developer.
