What is the use of functions? Write the general syntax of a JavaScript function.
What will be an ideal response?
When you want to reuse the same JavaScript commands throughout your Web page, you store the commands in a function. A function is a collection of commands that performs an action or returns a value. Every function includes a function name, which identifies it, and a set of commands that are run when the function is called. Some functions also require parameters, which are variables associated with the function.
The general syntax of a JavaScript function is
function function_name(parameters){
JavaScript commands
}
where function_name is the name of the function, parameters is a comma-separated list of variables used in the function, and JavaScript commands are the statements run by the function. Function names, like variable names, are case sensitive. A function name must begin with a letter or underscore (_) and cannot contain any spaces.
