Arrow Functions

Arrow functions offer several benefits over traditional function expressions. They provide a more compact syntax with less code, making your codebase more readable and maintainable.

Syntax

The syntax for an arrow function looks like this:

1const functionName = (parameter1, parameter2) => {
2 // Function body
3 // Code goes here
4};

The arrow (=>) separates the function parameters from the function body, which is enclosed in curly braces ({}). If the function has only one parameter, you can omit the parentheses around the parameter list. If the function has no parameters, you must include empty parentheses.

Examples

Here are a few examples to illustrate the usage of arrow functions:

1// Basic arrow function
2const square = (num) => {
3 return num * num;
4};

Instructions

1.

Change the sum function into an arrow function.

2.

Call and log the new sum function with two arguments of your choice.
