tower-of-babel

library1.0.0jsnpmunverified

A Node.js workshopper tutorial that teaches ES6 features through interactive exercises. Version 1.0.0 (last release circa 2015) is stable and uses Babel 6 with the es2015 preset. It is designed for offline command-line learning, with each exercise requiring the user to write code that passes a test. Differentiators: focuses exclusively on ES6 transpilation with Babel, as opposed to general ES6 tutorials. No longer actively maintained; superseded by modern environments with native ES6 support.

Verified usage

Verified import paths — ran on the pinned version, not inferred.

Default import pattern

✓ import fs from 'fs';

✗ const fs = require('fs');

ES6 import syntax is used throughout the exercises.

Named import pattern

✓ import { readFile } from 'fs';

✗ const readFile = require('fs').readFile;

ES6 named imports are encouraged.

Arrow function

✓ const add = (a, b) => a + b;

✗ function add(a, b) { return a + b; }

Arrow functions are a key ES6 feature taught.

Sets up a new project with ESLint, Babel, and starts the Tower of Babel tutorial.

Debug

Known issues

deprecatedTower of Babel uses Babel 6 and is no longer maintained. Modern environments support ES6 natively.

fix

Consider using native ES6 or a modern tutorial.

affects: *

getting errorRequires Node.js version 4 or lower. May fail on newer Node versions due to changes in module resolution.

fix

Use an older Node.js version (e.g., 4.x) or Docker to run the tutorial.

affects: >=10.0.0

gotchaThe .babelrc file must have presets set to es2015 for Babel 6. Babel 7 uses @babel/preset-env.

fix

For Babel 7, install @babel/cli, @babel/preset-env and set { "presets": ["@babel/preset-env"] } in .babelrc.

affects: >=1.0.0
