esbuild:tldr:b03f9

This command is using esbuild, a JavaScript bundler and minifier tool, to bundle, minify, and generate sourcemaps for a specific file. Here's a breakdown of each flag and its functionality:

• --bundle: This flag instructs esbuild to bundle the specified file along with any dependencies it has. It combines all the imported modules into a single file.
• --minify: This flag tells esbuild to minify the generated bundled code by removing unnecessary characters like whitespace and comments, reducing the file size.
• --sourcemap: This flag enables the generation of a sourcemap file (usually with a ".js.map" extension) that maps the minified code back to the original source code. Sourcemaps are useful for debugging minified code.
• --target=${chrome58,firefox57,safari11,edge16}: This flag specifies the target environment for the bundled code. In this case, the target environments are Chrome 58, Firefox 57, Safari 11, and Edge 16. Esbuild will ensure that the bundled code is compatible with these browser versions, applying any necessary transformations or polyfills.
• ${filename-jsx}: This is a placeholder for the actual filename (with a ".jsx" extension) of the JavaScript/JSX file that needs to be bundled.

Overall, this command will generate a bundled and minified version of the specified JavaScript/JSX file, including sourcemaps, while targeting specific browser versions.
