This chapter introduces loops, which allow JavaScript programs to repeat tasks automatically.
Instead of writing the same code again and again, loops help developers run a block of code multiple times based on a condition. This makes programs shorter, cleaner, and more powerful.
In this chapter, students will learn how to use different types of loops such as for, while, and do...while to perform repeated actions.
By the end of this chapter, you will be able to:
- Understand why loops are important in programming
- Use for, while, and do...while loops correctly
- Control loops using break and continue
- Perform repeated tasks like counting, searching, and listing items
- Build logic for real-world situations such as displaying lists, processing data, and running validations
This chapter helps students move from basic logic to writing efficient programs that can handle large amounts of data and repetitive work.
