JavaScript Arrow Functions
Arrow functions, provide a more concise way to write function expressions in JavaScript.
They're especially handy for callbacks or functions that don't require their own this context.
Here's a basic example of a regular function and an arrow function:
// Regular function
function add(a, b) {
return a + b;
}
// Arrow function
const add = (a, b) => a + b;
Key Points:
- Concise way of writing a function.
- If the function body is a single expression, neither the 'return' keyword or curly brackets are needed.
- They do not have their own 'this' context.
