Difference between Front-End vs. Back-end Developer

Difference between front-end and back-end developers In the website development process, it is usually divided into two pending parts, namely development on the back-end and front-end.
Both of these authorities have different roles in the website creation process, but both of them shoulder to shoulder with each other in order to produce good website products and can generate experience (UX) that impresses the users.

Sometimes some people find it difficult to distinguish between these two roles, there are still many debates that discuss the limits of what they are doing.

Front-end
Front-end developers or commonly known as developers on the client side (client-side), are people who focus their work on website appearance, nuances and user experience (UX) on a website.
Front-end is twisted with the design of the website and its flow, even now a front-end developer can take care of the processing of the API as well as the speed or performance of the website.

Skills needed by a front-end developer

• HTML - HTML is a markup language that is the basis for making a website until the website can be seen by users, all web pages on the internet are basically HTML.
• CSS - CSS can be considered cosmetic from HTML itself, CSS that makes the website look attractive, because with CSS we can create styles or styles for each tag in HTML.
  
  CSS has the ability to create grid layouts, typographic settings, provide color, even animation. If you see a button that is red and when the mouse is directed to the button then the color changes to another color so that it can happen because of the touch of CSS.
• Javascript - Javascript is a programming language that can make a website more interactive, Javascript can sometimes be the front-end domain but can also be back-end, but most Javascript is a front-end domain because Javascript is a client-side programming language. ), although Javascript is currently on the server side thanks to the growing development of NodeJS.
  
  Javascript, the main function is to make interactions for websites, because of the ability of javascript, we can create dialog boxes, dropdown menus, animations, and so on.
  
  Even now javascript allows front-end developers to become more broad-based roles, such as the ability to set routers on URLs, this is increasingly being used since users are increasingly busy with frameworks such as Vue, React and Angular.
• Image editing - Front-end developers also need to master image editing software such as Photoshop, or applications for website design such as Sketch, as well as applications for collaboration with UI such as Zeplin or MarvelApp or Figma.
• Cross Browser - Skill to ensure the appearance of a website can appear good and even similar to every browser that is currently the more value that front-end developers need, because today's users can open websites from various devices and various screen sizes.
• SEO - Search Engine Optimization is very closely related to the code on the website, so front-end developers also play a role here to make sure the code that is made supports SEO Friendly, such as writing code efficiently, trying to minimize server requests, and so on.

The task of the Front-end Developer

The tasks of front-end developers certainly depend on the project being worked on, including the scale. But at least what is commonly done by front-end developers is as follows.

• Develop all visual components on the website.
• Using HTML, CSS and Javascript in carrying out their main tasks to make website designs designed by UI designers more lively.
• Implementing wireframe becomes a real template that can be run in a web browser.
• Modify and maintain the interface of a website.
• The more modern front-end developers also process data APIs that are given to them and even manage the state to routing a website.
• Front-end developers also play a role in the speed of a website by implementing the task runner to a bundle module such as Gulp, Grunt and Webpack.

Back-end developer

Back-end developers are commonly known as people who specifically develop websites on the server side, the back-end focuses on functionality. Back-end developers also usually become architects of the technology used on a platform.

Development on this side can involve three important parts, namely servers, applications and databases.

Back-end developers are responsible for sending and receiving information displayed on the front.

Skills needed to become a back-end developer

• Java, PHP, Ruby, GoLang, Python, NodeJS & Javascript - The server-side programming language (except javascript) must at least be controlled by a back-end developer, not necessarily all, just a few, or even one that becomes his specialty.
• Database - A back-end developer deals with business logic, and one of the tasks of the back-end is to provide data supply for front-end developers, so mastering database is very important for a back-end developer.
• Code Versioning - Controlling the version of the code created is one of the skills that back-end developers must have at this time, because he has to make sure the program can be developed and may be returned to a more stable version when an error occurs during development, code versionong control like git / svn also really needs to be mastered if working with a team.
• Security - A back-end developer certainly has to think about the security of the application he made so that there are no gaps that can be exploited by others and potentially harm the company and even himself.

The task of Back-end developers

The task of a back-end developer can also depend on the scale of his work and the number of his team. But generally a developer will usually be responsible for the following:

• Server-side code writing
• Focus on the functionality and compatibility of the website
• Acting as an architect who designs website systems and technology
• Build a back-end system
• Make API functionality
• Memositos status from server

Additional skills for front-end & back-end developers

Apart from the skills we have discussed above, there are several other skills that must be possessed by these two fields to make them more qualified and more perfect.

Front-end developers need to be more creative and have extraordinary visualization skills, they also need to learn about the user experience (UX) in order to produce a charming and interactive interface.

Meanwhile back-end developers must have strong analytical and logical skills. In addition, they must also have the ability to solve problems and think critically in order to become reliable and quality back-end developers.
