One of the most common questions aspiring coders and software engineers have is, what is the best programming language to learn? No one wants to invest time learning a programming language that won't help them reach their career goals.
If you’re new to coding, you may wonder which languages are the most important to learn. The best programming language depends on what you want to build and the type of developer you want to be. It also depends on how much coding experience you have so far.
Below, this list will cover the best programming languages to learn and guidance on choosing the right ones for your career.
The best programming languages to learn
Before going through the list, let's briefly cover how we evaluated these as the best programming languages.
Best language criteria
- Learning curve: How hard is it for someone new to understand or use? For example, Python is easier to learn because its syntax—the structure of the language—is similar to English.
- Average salary: How does experience influence the average salary range?
- Use cases: What is this language typically used for?
- Community support: Is it easy to find communities and documentation to learn the language?
- Market demand: How many jobs need this skill and is it growing in demand? Do popular applications or companies use it?
- Best for roles: Which jobs use this programming language daily?
Now that we have that covered, let's dive into the list.
1. HTML and CSS
HTML and CSS are technically two, but we’ve combined them in this list since they’re so closely connected.
HTML or HyperText Markup Language is the structure of any webpage you see online in a browser. With it, you can add headings, bullet points, and images to a page. Screen readers also use HTML to understand and describe the content on a page for those with visual impairments.
Developers use Cascading Style Sheets (CSS) and HTML together. CSS is how you ‘style’ or bring HTML to life. It’s how you add colors, animation, layouts, mobile responsiveness, and typography.
HTML and CSS aren't technically programming languages but are required for front-end web development or web design. Of course, front-end developers typically have to learn JavaScript too.
Learning curve
HTML and CSS are the easiest languages to learn. On average, developers take about one month to get the fundamentals down. Advanced topics like responsive design—developing a webpage that adapts to multiple devices and screen sizes—may take longer to learn.
Salaries
A web designer role may suit you if you specialize in HTML and CSS. According to Glassdoor data, the average web designer’s salary for a year is:
- Entry-level: $49,000
- Mid-level: $66,000
- Senior-level: $106,000
Keep in mind that this is an average. It doesn't account for benefits, location, cost of living, or experience, which influences your compensation.
Market demand
According to the US Bureau of Labor Statistics(opens new window), demand for web designers with HTML and CSS knowledge is expected to grow by over 16% in the next decade. This translates to over 17,000 new jobs each year.
Use cases
Web designers use a combination of creative and technical skills. Types of projects web designers work on could include:
- User design: The layout and aesthetic of a site and how users interact with it.
- Front-end development: Designing and developing the front-facing part of a new website or existing site.
Community support
Almost everything on the Internet, from Twitter to LinkedIn, was built with HTML and CSS. You'll have plenty of online communities and resources to support you while learning.
Best roles
- Web Designer
- Front End Developer
- Web Developer
2. JavaScript
HTML and CSS create static elements. You see them, but you can’t interact with them. JavaScript is what makes sites interactive.
For example, you see buttons on all websites. They may say “Submit” or “Add to Cart”. HTML tells the browser that the element is a clickable button. CSS styles the button font, border, size, and color to stand out on the page.
With only HTML and CSS, clicking the button wouldn’t do anything. You haven’t told the browser what you want the button to do. You need to add JavaScript to tell elements on the page what to do.
JavaScript goes beyond buttons. You can create complex, interactive features like social media news feeds or maps with JavaScript.
Learning curve
JavaScript has a medium-level difficulty compared to the other programming languages on the list. On average, learning JavaScript will take new developers about three to six months.
Salaries
The average JavaScript Developer's salary is:
- Entry-level: $80,000
