How do you create a function in JavaScript?

Creating a function in JavaScript primarily involves using the function keyword. When you declare a function, you start with this keyword, followed by the function name and parentheses. The parentheses can include parameters that the function accepts. For example, you might write:

function myFunction(param1, param2) {

// function body

}

This structure clearly indicates that you are defining a reusable block of code that can be invoked by its name. The use of the `function` keyword is essential because it differentiates a function declaration from other statements in JavaScript.

While there are other ways to create functions, such as assigning them to variables or using arrow functions, the question specifies the traditional method of function creation which is accurately described by using the `function` keyword followed by the function name and parentheses. This method is foundational in understanding how functions operate in JavaScript.
