Is The Modern JavaScript Tutorial suitable for beginners?

Yes, for motivated beginners who can read English and are comfortable using a browser-based developer console. The Modern JavaScript Tutorial (javascript.info) explicitly says it teaches JavaScript "starting from scratch" and then moves to advanced concepts like OOP, so it is designed to take a learner from zero to a fairly deep level. The main caveats are that it is text-heavy, assumes you will do the exercises, and does not hold your hand with video or a structured course schedule.

What the tutorial actually covers

The site organizes its material into three parts, which makes the progression easy to see:

For a beginner, Part 1 is the natural starting point. The opening sections are deliberately gentle: "An Introduction to JavaScript," "Hello, world!," "Code structure," "Variables," and "Data types" come before anything advanced. From there the difficulty ramps up steadily through functions, objects, and eventually asynchronous programming.

Why it works for beginners

• It starts from scratch. The site states that it begins with the basics and goes on to advanced concepts, so you are not expected to already know another language.
• Examples and tasks are built in. The description mentions "examples and tasks," and the table of contents shows a task-oriented structure. Doing the tasks is what turns reading into learning.
• It explains the "why," not just the "how." Topics like closures, prototypal inheritance, and the event loop are covered with detailed explanations rather than one-line definitions, which matters when you hit the parts that confuse most newcomers.
• It is self-contained for the language. Part 1 concentrates on JavaScript itself with minimal environment-specific notes, so you can learn the core language without first setting up a complex project.

Where beginners struggle

• It is a tutorial, not a course. There is no instructor pacing you, no deadlines, and no certificate. You have to supply your own consistency.
• It gets hard quickly. After the fundamentals, the material moves into closures, prototypes, classes, and async/await. These are genuinely difficult topics, and the tutorial does not slow down much.
• English is required. The site's language is English, and the explanations are detailed, so strong reading comprehension helps.
• You need to actually run code. Reading alone will not be enough. You should have a code editor and a browser developer console ready, and you should type out and modify the examples.

A practical way to use it as a beginner

1. Start at "An Introduction to JavaScript" and work through Part 1 in order. Do not skip the early sections even if they look trivial.
2. After each section, open your browser's developer console or a code editor and retype the examples from memory.
3. Do the tasks at the end of each section before moving on. If you cannot solve one, re-read the section rather than looking up the answer immediately.
4. Treat the advanced sections (closures, prototypes, async) as a second pass. It is normal to need to revisit them.
5. Only move to Part 2 (Browser: Document, Events, Interfaces) once you are comfortable with the language fundamentals in Part 1.

Who should look elsewhere

If you need video instruction, a fixed schedule, or a classroom environment, this tutorial will likely feel dry. If you want to build a specific app immediately rather than learn the language systematically, a project-based course may suit you better. But if you want a thorough, free-to-read reference that takes you from "Hello, world!" to advanced JavaScript, this is one of the most complete options available.
