How to create a function in JavaScript?

Rating:

Functions can be considered as sub-programs that are defined to perform different actions. Functions can be invoked within another function or invoked by an event handler of an object. They are defined by using the function keyword followed by a set of parentheses. A function cannot be created within another function, but it can be called by another function. In JavaScript, functions are defined to perform different actions such as performing calculations, creating objects, referencing objects, etc.

The syntax for declaring a function is as follows:

function myfunc()
{
       //statements
}

The syntax for invoking a function is as follows:

<input type="button" value="Click Me" onclick="myfunc()">
