In JavaScript, what keyword is used to define a function?

In JavaScript, the keyword used to define a function is "function." This keyword initiates the declaration of a function, allowing you to define reusable blocks of code that can be executed when called. The syntax typically looks like this:

function functionName(parameters) {

// code to be executed }

When using the "function" keyword, you can specify the function's name, which is essential for calling the function later in the code. Additionally, you can include parameters within parentheses to pass values into the function, enabling it to act on inputs and return results.

The other terms listed, such as "def," "method," and "procedure," are not used in JavaScript. "Def" is used in Python, while "method" typically refers to functions that belong to objects in object-oriented programming contexts. "Procedure" is not a standard JavaScript term; it often relates to similar concepts in other programming languages. However, in JavaScript, functions serve both the roles of procedures and methods, but the defining keyword remains "function."
