How does typescript.isImportEqualsDeclaration work?

typescript.isImportEqualsDeclaration is a function that determines whether a given node is an ImportEqualsDeclaration node in a TypeScript AST (Abstract Syntax Tree) by examining its properties and structure. It returns a boolean value indicating whether the node is an import equals declaration or not. The function checks if the Node's kind property is ts.SyntaxKind.ImportEqualsDeclaration.

import ts from "typescript";

const sourceFile = ts.createSourceFile(
  "example.ts",
  "import example = require('./example');",
  ts.ScriptTarget.ESNext
);

if (
  sourceFile.statements[0] &&
  ts.isImportEqualsDeclaration(sourceFile.statements[0])
) {
  console.log("This is an ImportEqualsDeclaration!");
} else {
  console.log("This is not an ImportEqualsDeclaration.");
}

In this example, typescript.isImportEqualsDeclaration is used to check whether the first statement in a source file is an ImportEqualsDeclaration. If it is, the function logs a message to the console indicating that it is indeed an ImportEqualsDeclaration, otherwise it logs a message saying that it is not.
