In the ever-evolving world of JavaScript, arrow functions have emerged as a concise and elegant way to write function expressions. Introduced in ES6 (ECMAScript 2015), arrow functions not only provide a more compact syntax but also offer several benefits that can enhance code readability and maintainability.
In this article, we’ll explore the fundamentals of arrow functions, their syntax, and practical examples to help you understand and leverage their power.
What are Arrow Functions?
Arrow functions, also known as “fat arrow” functions, are a shorthand syntax for defining function expressions in JavaScript. They are called “arrow” functions because they use the “fat arrow” (=>) notation to define the function body.
Unlike traditional function expressions, arrow functions have a more concise syntax and automatically bind the this value to the surrounding lexical scope.
