Why would I use TypeScript and Babel together? [closed]
In my opinion you transpile TypeScript code to ES6 by using typescript and then re-transpile it to es5/es3 using babel to use in most javascript run times. Now because typescript compiler gives you es6 javascript you can do tree-shaking which is only supported for es6 module. And after tree-shaking your es6 javascript you can now compile it down to es5 to be able to used by most of the javascript run times out there.
Basically
- Compile ts to js-es6
tsconfig
{ "compilerOptions": { "target": "es6" }}- tree shake or dead code elimination in es6 javascript
Tree ShakingUsing rollup etc
- Transpile to es5 javascript to be able to run in most of the javascript runtimes
.babelrc
{ "presets": [ "es-2015", "stage-2" ]}
