What keyword is used to define a function in JavaScript?

In JavaScript, the keyword used to define a function is "function." This keyword signals the start of a function declaration and is essential for establishing a block of reusable code that can perform a specific task.

When you write a function, you begin with the "function" keyword, followed by a name for the function, parentheses for parameters (if any), and a pair of curly braces that enclose the code to be executed when the function is called. For example:

function myFunction() {

console.log("Hello, world!");

}

Without the "function" keyword, JavaScript would not recognize that you are attempting to define a function, thus leading to syntax errors or unexpected behavior. Other terms like "func," "define," and "create" do not have any significance in JavaScript function definitions and are not recognized by the language's syntax. Therefore, "function" is the correct and only keyword for defining a function in JavaScript.
