TypeScript Playground vs webpack

TypeScript Playground is a free browser environment for writing, running, sharing, and safely experimenting with TypeScript and JavaScript. It accepts .ts, .tsx, .js, .jsx, and .d.ts files. Run converts code to JavaScript, executes it in the current browser session, and shows console output in Logs; the browser session can also support DOM API experiments. The editor centers on one text document and is described as a teaching tool that needs no setup. Users can select supported TypeScript builds, including beta, nightly, pull request, and older builds. The TS Config panel exposes a focused compiler-option set, while twoslash annotations can configure options beyond it. URLs can preserve code, compiler flags, and settings for sharing. Export can create Markdown, open TypeScript AST Viewer, or export a project to CodeSandbox or StackBlitz. Plugins are supported, including Presentation Mode, Clippy, TSQuery, Collaborate, and Transformer. The mobile layout uses a single pane and does not show transpiled JavaScript beside source.

webpack is a free, open-source static module bundler for modern JavaScript applications. It builds a dependency graph and combines modules into bundles, with code splitting for on-demand loading. Built-in support covers JavaScript, JSON, WebAssembly, CSS and HTML. Loaders transform sources such as Sass into CSS or TypeScript into JavaScript, while plugins customize compilation through lifecycle hooks. ModuleFederationPlugin lets independently built applications share modules at runtime. Since version 4.0.0, webpack can run without a configuration file, although it remains highly configurable. Interfaces include the CLI, Node API, loader API and plugin API, and documentation covers integrations with Browserify, Brunch, Grunt, Gulp, Mocha and Karma. The project recommends local npm installation and a fresh Node.js installation; command-line use from webpack v4 onward also requires webpack-cli. The MIT-licensed software supports tree shaking and source maps. CSP is not enabled by default, and native CSS and HTML support are experimental.
