Which JavaScript function is used to define a method in a class?

In JavaScript, methods within a class are defined using a specific syntax that closely resembles a function declaration, but with the inclusion of the method name directly after the class definition. The correct choice highlights a standard way to name a method.

When creating a class in JavaScript, you define methods by stating their names followed by parentheses for parameters and then including a block of code within curly braces. For example, within a class:

class MyClass {

methodName() {

// method logic here

}

}

This directly illustrates how to establish a method within a class context. The method name in this case serves as an identifier to be called upon, distinguishing it from other functions or class properties.

The other choices do not align with the conventions or syntax used for defining methods in classes. For instance, while functionName(){} could represent a standalone function, it does not encapsulate the necessary context of being a method within a class. Other options like defineMethod(){} and createMethod(){} suggest specific naming but do not follow the standard naming conventions set in JavaScript for method definitions in classes, leading to confusion and misalignment with the expected syntax.
