🥧Implicit Return

In JavaScript, a function can return a value to the code that called it. This value is the result of the function's execution. A function can return a value using the return keyword. When the return keyword is used, the function's execution stops and the value is returned

function add(a, b) {
  return a + b;
}

let result = add(2, 3);
console.log(result); // Output: 5

An implicit return is a way of returning a value from a function without explicitly using the return keyword. This can be done by using arrow functions, which have a shorthand syntax that allows you to omit the return keyword when the function only has one expression.

let add = (a, b) => a + b; 

let result = add(2, 3);
console.log(result); // Output: 5

In the example above the function add is an arrow function that takes two parameters a and b. The code inside the function a + b is the only expression inside the function, and it is implicitly returned.

An implicit return can also be done with the use of a single line function block, you don't need to use the return keyword and the curly braces if the function only has one line of code:

function double(x) { return x*2 }

can be written as:

const double = x => x*2;

It's important to note that implicit return only works when the function has a single expression, if you want to return an object, you will need to wrap it in parenthesis, like this:

const myFunction = () => ({ key: 'value' });

In summary, an implicit return is a way to return a value from a function without explicitly using the return keyword, it can be achieved by using arrow functions and single line function blocks, it's a shorthand that can make the code more concise and easier to read.
