What are @types/acorn's main functionalities?
Type Definitions for Acorn Parser
This code sample demonstrates how to use the @types/acorn package to provide type definitions when using the Acorn parser to parse a piece of JavaScript code. It sets up parser options with type safety and parses a simple script, logging the resulting AST.
import * as acorn from 'acorn';
const options: acorn.Options = {
locations: true,
ecmaVersion: 2020
};
const code = `let x = 10;`;
const ast = acorn.parse(code, options);
console.log(ast);
Other packages similar to @types/acorn
@types/esprima
Provides TypeScript definitions for Esprima, another popular JavaScript parser. Similar to @types/acorn, it helps in integrating Esprima with TypeScript projects by offering type definitions. Both packages serve a similar purpose but for different parsers.
@types/babylon
Now known as @babel/types, this package offers TypeScript definitions for the Babylon parser used by Babel. Like @types/acorn, it provides type safety for developers parsing JavaScript code in TypeScript projects, but it is tailored to the Babylon parser used within Babel's ecosystem.
