    Frequently Asked Questions (FAQ)

    All websites require both front-end and back-end development. The front-end part of a website is what users see when they open the website and interact with it. The way everything works is the back end coming into play. The two sides need to communicate smoothly in order for the website to perform flawlessly. When combined together, the front-end and back-end create a harmonious relationship and result in interactive and visually appealing websites.

    Here is the table explaining each side of website development:

    What they do 
    Front-end developers

    They design the visual (physical) part of a website with different front-end programming languages. The results of their work include what you see on a page: fonts, colors, layout, and graphics. 

    Back-end developers

    A back end developer builds the core of the website – the structure and logic behind it by using server-side programming languages. In other words, they write code to tell the web page how the front-end part must function. 

    Average salary 
    Programming languages
    JavaScript, HTML, CSSPython, Java, Ruby, PHP
    Frameworks and libraries 
    jQuery, AngularJS, SASS, Bootstrap, EmberJSDjango, Laravel, Spring, Zend, Symfony, CakePHP

    In other words, front-end development is responsible for the client side, while back-end supports the server side. However, it’s important to remember that front-end developers don’t design the front-facing elements of a web page – it’s the duty of a UI designer. Then, the front-end developer takes this design and creates a functional website with the front-end languages.

    The duration of back-end development can vary widely depending on several factors, including the complexity of the project, the size of the development team, the back-end development services you need, the technology stack being used, and the specific requirements of the project.
