Passing Parameter in Function

In JavaScript, you can pass parameters to functions, allowing you to provide data or values that the function can use during its execution. Parameters are specified in the function declaration or definition, and they act as placeholders for the values that will be passed when the function is called.

The syntax of function is:

// Function is called, the return value will end up in x
data_type variable = myFunction(parameter);
function func-name(parameter) {
    // Function returns the product of a and b
    return operation;
}

Here's an explanation of how to pass parameters to functions in JavaScript:

Function declarations define the structure of the function, including its name and parameters. Parameters are enclosed in parentheses following the function name.

Example:

function greet(name)
{
    console.log('Hello, ' + name + '!');
}

In this example, the greet function is declared with a name parameter. This parameter represents the value that will be passed to the function when it is called.
