Introduction

After mastering the foundational technologies of Web development: HTML, CSS, & JS, lots of developers wonder about how many more tools they really need to learn. In this growing age of technology where languages and frameworks are constantly developing, you may feel behind as a developer for not being able to keep up.

This is a dilemma that conflicts with many junior developers who are just learning their first technologies and who are getting into the field of development. In this blog, we will go over how many programming tools a developer should really have to learn, which technologies developers should and shouldn’t focus on, and how their specific specialty may affect which skills they should focus on.

The Truth

The blunt truth is that there is no straight answer or number to how many programming tools a developer should learn. It all really depends on what development field they specialize in. Being a web developer isn’t a single job. Some developers specialize in the front end, while others specialize in backend, etc…

Frontend Specialists:

Front end developers should have a fluent understanding in javascript. For them, having depth in knowledge here matters more to them than anything else. This means they should be working on mastering modern frameworks such as Vue or React & getting used to their syntax. Additionally, Typescript is also a good technology to know as a frontend developer, as it shares syntax structure and has similar logic, and it’s a popular choice for large-scale development.

Backend Specialists:

Backend is a diverse field, as there are many ways to go about maintaining the back end of websites. Backend developers should try to focus on a wide range of backend systems to have a good fluency and understanding of their specialty.

For backend developers, their skillsets must be more diverse, as they need fluency in more technologies compared to some other specialties. For example, they may need to know:

  • Node.js to communicate JS with the server
  • Python to incorporate data science libraries and utilize its clean syntax
  • PHP
  • SQL for database interaction
  • Etc…

For UI-Focused Developers:

For developers focused on UI/UX development, they do not need to know any complex programming as others do. Instead, they should focus on having mastered HTML and CSS to an artistic extent, where they can manipulate HTML and CSS styling to express their creativity ideas and designs easily. They may also need to know some Javascript for interactivity, but nothing advanced. They won’t need to touch on any libraries or frameworks as simple design tweaks do not require that much level of coding.

What languages shouldn’t you learn?

You don’t need to learn every tool out there as a developer. Depending on your specialty, there are some systems that you probably shouldn’t even ever have to worry about. Although it would be good to know a thing or two about them, you probably will never touch on them or need to touch in on them. For example, a UI/UX developer should not have to know technologies such as SQL or Node.js because those systems are back-end and server-side focused—which do not relate to UI/ design development.

You shouldn’t have to learn in-depth knowledge or fluency in tools that don’t have much relation to your specialty, as you will not use them much.

Conclusion

Instead of counting languages, one should first build a solid foundation by knowing what they’d need to have fluency in for their specialty, and then build on their knowledge by also having some insight on other languages. For example, even though a backend developer only really needs to know languages such as PHP, SQL, Node.js, etc.., they should also have knowledge of HTML and CSS in order to know how things work and to add to what they already know.

Ultimately, a developer should learn languages in order to solve problems that they face, not to collect them. They should focus on tools that support and work alongside their specialty. In this blog, we went over the question of “How Many Languages Should You Really Learn as a Web Developer?”, different specialties and what languages they should focus on, and what languages they shouldn’t focus on. Now that you’ve read about this topic, what languages do you need to learn to succeed as a developer?
