• asyncWebAssembly: Support the new WebAssembly according to the updated specification, it makes a WebAssembly module an async module
• topLevelAwait: Support the Top Level Await Stage 3 proposal, it makes the module an async module when await is used on the top-level
• outputModule: enables the use of output.module configuration option and sets it to true. Enables the use of output.libraryTarget as 'module' and sets it to 'module'.
• layers: Enable module and chunk layers.

  experiments: {
    outputModule: true,
    syncWebAssembly: true,
    topLevelAwait: true,
    asyncWebAssembly: true,
