Unit testing is the process of testing individual blocks of code, and unit testing frameworks provide a specific method and structure for doing so. The big idea with unit testing is that you write “tests” in code that test your other code, and you can do it with any programming language, including JavaScript. UI is the graphical layout of an application that determines what each part of a site or application does and how it will look. “I’ve always found crafting polished user interactions that surprise and delight users to be the most rewarding and engaging task,” says Mari Batilando, a software engineer at Meta. “In order to do this, you need to both have an eye for detail and a rock-solid understanding of the platform.”

The BLS projects there will be 20,900 new web developer jobs between 2018 and 2028, a 13% growth in the market. That rate is nearly three times the national job growth frontend developer courses average during the same span (5%). Over 6,700 of the web developer jobs will be created in computer systems and related design, a 24.3% jump in that industry alone.
Programs
As a professional frontend developer, you should be familiar with APIs and how to consume and manipulate them. This is critical for communicating with backend logics and databases. HTML is frequently the first language that developers learn, and it is essential for front-end development work. Begin with freeCodeCamp’s Responsive Web Design certification and Beau Carnes’ brand new full HTML course. HTML stands for Hyper Text Markup Language, it is the skeleton of all web pages and applications as thier most basic building block. You use HTML to structure your page into elements such as paragraphs, sections, headings, navigation bars, and so on.
For example, a developer might want to integrate weather data into their website. They could use an API that reaches out to a weather service and gets the data. An API (Application Programming Interface) allows an application or service to access a resource within another application or service. When you start typing a search query into Google, the search engine will offer you auto-complete options. It can do this without reloading the entire search results page. That means that you can update the web content on a portion of a webpage without reloading the entire page.

As a result, you end up with professional and mobile-friendly designs. After completing the course, you will be able to starting building small web pages. Everything on the page from the logo to the search bar, buttons, overall layout and how the user interacts with the page was created by a front end developer.
There are various software applications used as front-end web development tools, including but not limited to HTML, CSS, and JavaScript tools. A client’s needs and requirements can help determine what tools are used in front-end web development for their particular website. Because tools are constantly being developed and updated, front-end web developers can benefit from staying informed about changes and upgrades. Various front-end web development tutorials, advanced programs, and coding boot camps are available online to learn front-end web development.
