How does typescript.updatePropertyAssignment work?

typescript.updatePropertyAssignment is a function provided by the TypeScript compiler API that allows updating the properties of a TypeScript PropertyAssignment node.

This function takes three arguments: the original PropertyAssignment node, the new name of the property, and the new initializer value to be assigned to that property. It creates a new PropertyAssignment node with the updated values and returns it, without modifying the original node.

import ts from "typescript";

const node = ts.createPropertyAssignment(
  ts.createIdentifier("name"),
  ts.createStringLiteral("John")
);

const updatedNode = ts.updatePropertyAssignment(
  node,
  node.name,
  ts.createIdentifier("firstName")
);

In this example, we create a PropertyAssignment node with the name "name" and a value of "John". We then use ts.updatePropertyAssignment() to create an updated version of this node, changing the name to "firstName". The result is a new PropertyAssignment node with the name "firstName" and a value of "John".
