This chapter introduces ES6 and modern JavaScript features that are widely used in today’s professional development.
ES6 (ECMAScript 2015) brought many powerful improvements to JavaScript, making code cleaner, shorter, and easier to maintain. Modern JavaScript now looks very different from old-style scripting.
These features are used in almost every real-world project, framework, and library such as React, Vue, Node.js, and modern browsers.
In this chapter, students will learn how to:
- Use let and const instead of var
- Write cleaner code with arrow functions
- Work with template literals for dynamic strings
- Use default parameters and rest/spread operators
- Destructure arrays and objects
- Organize code using modules
- Write modern, readable, and professional JavaScript
By the end of this chapter, students will be comfortable writing modern JavaScript code that follows today’s industry standards — an important step toward becoming a job-ready developer.
