2. Time Commitment to Learn JavaScript
One of the first questions aspiring developers ask is, “How long will it take to learn JavaScript?” While there’s no one-size-fits-all answer, here’s a general timeline:
- Basic Syntax and Concepts: Expect to spend a few weeks to a couple of months grasping the fundamental syntax, data types, variables, operators, control flow statements (if/else, loops), and basic functions.
- DOM Manipulation: Learning how to interact with the Document Object Model (DOM) is crucial for dynamic web development. This typically takes a few weeks of practice, understanding how to select elements, modify their content, and respond to user events.
- Asynchronous JavaScript and AJAX: Understanding asynchronous programming (handling tasks that don’t block the main thread) and AJAX (making requests to servers without reloading the page) can take several weeks to master. These are essential for creating responsive web applications.
- JavaScript Frameworks: Learning a JavaScript framework like React, Angular, or Vue.js can add a few months to your learning journey. Each framework has its own concepts and best practices to learn.
- Advanced Topics: Delving into advanced topics like closures, prototypes, higher-order functions, and design patterns can take several months or even years of continuous learning and practice.
According to a study by CodingNomads, most of their graduates are able to gain junior developer roles after around 3-6 months intensive study. These are also the figures quoted by bootcamps such as Flatiron School and General Assembly.
| Learning Stage | Estimated Time |
|---|---|
| Basic Syntax and Concepts | 2 weeks – 2 months |
| DOM Manipulation | Few weeks of practice |
| Asynchronous JavaScript/AJAX | Several weeks |
| JavaScript Frameworks | Few months |
| Advanced Topics | Several months – years |
3. Is JavaScript the Hardest Language to Learn?
Compared to some other programming languages, JavaScript is often considered to be moderately difficult to learn. Here’s a comparison:
- Python: Python is known for its clear syntax and readability, making it a popular choice for beginners. JavaScript can be slightly more complex in terms of syntax and concepts.
- Java: Java is a statically-typed language with a more verbose syntax than JavaScript. Many find JavaScript easier to pick up initially but Java to be easier to maintain in larger projects.
- C++: C++ is a lower-level language that requires a deeper understanding of memory management and system-level concepts. JavaScript abstracts away many of these complexities, making it generally easier to learn.
- Ruby: Ruby is another dynamic language with a focus on simplicity and elegance. Both Ruby and JavaScript are relatively easy to learn, but JavaScript has the advantage of being essential for front-end web development.
Kimbarovsky believes that understanding JavaScript as a language before tackling a JS framework is extremely important. Without a higher level view of JavaScript, Kimbarovsky says, you won’t truly understand how a JS framework works—meaning you’ll ultimately be limited in what you can use it to do.
