How to Become a Web Developer
What Skills Do You Need to Be a Web Developer?
As the core of web development work involves writing code, Web Developers must have advanced programming skills, and be fluent in a number of programming languages and libraries.
What Is a Programming Language?
A programming language is a system of symbols and words with syntactical rules that can be used to control the resources of a computer – namely the CPU, memory, and inputs/outputs such as a keyboard, mouse, and monitor. Computers are electrical devices that are controlled by electrical signals in the form of low/high voltages, which are known as 0 and 1. A computer, therefore, understands a series of signals made up of 0s and 1s, or binary.
For humans, writing in binary is very difficult, so having human-like languages that can be translated down to these 0’s and 1’s makes controlling computers much easier. However, there is no one universal programming language and all programming languages are eventually translated down to 0s and 1s.
Similarly, in the human world, there is not one human language. There are many families of human languages – some with obvious relationships and evolutions, while others are completely separate and unrelated. All humans have similar experiences in life and numerous languages have all evolved different ways of expressing those experiences.
Many computer languages share fundamental concepts, just like human languages do, even though syntactically, they can look different. Some programming languages are very domain specific – for example, some can be used to control a specific electrical device – while others are so general that they can be used on virtually any computer or device and can solve any problem.
Programming languages that are closer to a problem domain, and more human-like and abstract, are called “high-level” programming languages. Languages that are more computer-like in their syntax and terminology are considered “low-level” programming languages.
High-Level vs Low-Level Programming Languages
All programming languages are based around some fundamental paradigm or a set of paradigms, that form the conceptual approach to using that programming language – and there are numerous programming paradigms. This affects the expressiveness of a language, and how easy it is to solve various problems. Some common programming paradigms include:
Functional: Conceives of a problem as solved through a series of “functions” that, given the input, return a result. By putting together these functions, you can achieve the result you want.
Object Oriented: Conceives of a problem as a system of objects that interact with each other, like in the real world. Objects have properties and actions that they can take, and can manage their own state.
Imperative: A more literal, computer-like paradigm that conceives of a problem as a series of instructions for the computer, such as accessing computer memory, creating branches of instructions, and using indices to control repeating code.
Event-Driven: Conceives of a problem as a series of events that can happen at any time, in any order. This is important because events are unreliable – anything can happen. So, a Programmer defines what they want to happen when an event occurs, without worrying about when exactly that event will happen.
Choosing Your First Programming Language
For your first, you will often be learning a general programming language that incorporates some or all of these paradigms. These are mainstream languages that have numerous resources available to learn from.
Learning any of these languages will give you a strong understanding of what computers are about, and allow you to develop your programming skills. So while choosing your first language can seem like a daunting task, getting started is far more critical, no matter what language you choose. In fact, most programmers today probably do not program professionally in the language they first learned, and have since learned additional languages.
Practical Considerations When Choosing a Programming Language to Learn
Most people who are looking to learn a programming language are approaching it pragmatically, as in “Which programming language is most likely to help me get a job the fastest?”
From a practical perspective, the choice of a programming language depends on two main factors: Industry and Domain.
Different industries might favor certain programming languages. For example, many enterprise web applications, such as banks, use Java or C# for much of their infrastructure. The age of an industry or company can also affect the tech stack used – many SaaS companies started in the early 2000s were developed using PHP and may continue to use it.
If your goal is to get a job, getting to know your ideal workplace and industry can help decide what language you should focus on. Job postings are a good place to start; if companies you’re interested in seem to be asking for a particular language, that’s something to consider.
Some languages are more widespread than others, and you might find learning those languages easier and more broadly useful. There are also more niche programming languages, which can be useful, but which might limit your job opportunities.
When choosing a first language, it’s important to remember that languages increase or decrease in popularity and evolve over time, with new languages emerging that are more powerful and effective than previous languages or versions.
What Essential Skills Should Every Web Developer Have?
HTML and CSS. Hypertext Markup Language (HTML) and Cascading Style Sheets (CSS) are the foundation of any Web Developer’s knowledge. HTML is the standard markup language used to build web pages, while CSS enables you to program the appearance of the web page, with things like colors and fonts. Together, HTML and CSS are the building blocks for web development.
Structured Query Language (SQL) is a programming language that is designed to manage, query, and manipulate data stored in a database.
Python is an object-oriented programming language used for many data science applications, including machine learning.
Beyond programming languages and libraries, becoming comfortable with commonly used tools like Git, or other version control software is a skill every Web Developer should have. Version control is a method of tracking different versions of code to ensure you can access it or restore it at any time.
There are also a number of design skills that are useful for Developers to have, with an understanding of responsive design being perhaps the most crucial. Responsive design is a method of web design that ensures a website responds to the screen size or platform used to view the content. With over 52 percent of global web traffic coming from mobile phones, 43 percent from desktop, and the remainder from tablets, the screen size used to view websites is extremely varied. To ensure that the experience is seamless across all platforms and screen sizes, Developers must be fluent in responsive design.
While Web Developers are not typically tasked with the overall site design, it’s an advantage for Developers to also have a solid understanding of common design principles. Front-End Developers, in particular, program the screens that users interact with – they can be far more successful with a good grasp of user-centered design.
What Soft Skills Do You Need to Become a Web Developer?
As Developers must work with diverse teams, there are also a number “soft skills” that are important to develop:
Communication. From design, to marketing, to management, Developers are in communication with a host of departments to create products and services. Effective communication is essential to stay on track and complete projects.
Problem-solving. Because a portion of every Developer’s day involves debugging and maintenance, problem-solving skills are high on the list of requirements. Developers need to think critically and find creative workarounds and solutions where others have failed. They’ll also have to work independently when need be.
Time management. Developers are frequently tasked with multiple short-term and long-term projects, and must know how to prioritize tasks and accurately gauge time-to-completion. Having excellent time management skills also makes working with large teams easier, resulting in timely project delivery.
