🔓 Function

JavaScript function is a block of code designed to perform a particular task.

We have actually used a function many times without us knowing, that is alert(),which displays an alert box with a specified message on it.

A function is written with the **function**keyword, followed by a name of the function, and a parentheses ().

This is how we create a function.

function name_of_function (parameters){
    //code to be executed
}

ℹ️ parameters can be empty () if there is no argument to be passed in.

For instance, i would like to create a function named greet, that will pop up a hi message with the user's name when he or she login. This is how i do it:

function greet (name){
    alert("Hi, " + name);
}
