How does @babel/types.isClassMethod work?

@babel/types.isClassMethod works by taking an AST node as input and checking whether it represents a class method.

The function returns true if the node is an object of type ClassMethod in the AST, indicating that it is a class method, and false otherwise.

A class method is a function that is defined inside a class declaration or expression and has access to the class instance through the this keyword.

By using @babel/types.isClassMethod, developers can easily check whether a given AST node represents a class method, and use it to perform various operations on the node if it does.

This can be useful when working with complex code transformations and refactorings that involve modifying class declarations or expressions.

const t = require("@babel/types");

const node = t.classMethod(
  "method",
  t.identifier("myMethod"),
  [],
  t.blockStatement([])
);

const isMethod = t.isClassMethod(node);

console.log(isMethod); // true

In this example, we use @babel/types.isClassMethod to check whether an AST node represents a class method. We first create an AST node using the t.classMethod() method, which creates a new ClassMethod node. We then pass the node to t.isClassMethod() to check whether it represents a class method. The function returns true because the node is a ClassMethod node, indicating that it represents a class method. By using @babel/types.isClassMethod in this way, we can easily check whether a given AST node represents a class method, and use it to perform various operations on the node if it does.

  value.returnType = node.returnType;
