JavaScript Coding Exercises: Coding for Beginners

JavaScript becomes easier to approach when a small idea turns into a working result. JavaScript Coding Exercises: Coding for Beginners by JJ Tam offers a collection of short programming examples built around familiar tasks—from displaying the date and time to manipulating text and calculating numbers.

Rather than focusing on lengthy theory, the book gives beginners concrete snippets to examine and try. Its exercises also touch on the connection between JavaScript and a web page, including simple browser actions and form-based calculations.

Start with familiar problems 💻

The examples cover practical fundamentals such as checking whether a year is a leap year, finding the area of a triangle, multiplying or dividing two values, and converting temperatures. These approachable prompts give new coders a way to see how JavaScript instructions can be used to produce a specific result.

Work with strings, numbers, and dates

Alongside calculations and date-and-time displays, the collection includes string-focused tasks: reversing text, counting vowels, capitalizing an initial letter, and checking the beginning of a string. Taken together, the examples offer practice with several everyday kinds of input and transformation.

See JavaScript in a browser context

Some snippets pair JavaScript with basic HTML, such as a button that prints the current page or a small form that displays a multiplication or division result. This gives readers a glimpse of how code can respond to browser elements, not just perform calculations in isolation.

A compact practice companion

JJ Tam’s collection is suited to beginners who want bite-sized examples to read, test, and adapt as they get acquainted with JavaScript. Keep a code editor or browser console nearby, try each idea, and notice how changing the inputs changes the result. 📚
