Compiler treats javascript files like declaration files and does not emit any output corresponding to them. Here are the list of work this PR supports:

  • Allow javascript files to be compiled on command line or through references/imports
  • tsconfig.json can take javascript files as file names to be compiled
  • If filenames are not specified in tsconfig.json, javascript files in the folder and not part of compilation
  • compiler options now have a flag named "consumeJsFiles" which when true will pick up javascript files in the folder for compilation if tscconfig.json doesn't supply file name list
  • Moved reporting of usage of typescript syntax in javascript file from services to compiler
  • Reports error if output is overwriting any of the input files
  • Reports error if output is not unique location and multiple input files overwrite same output file
  • It is error to reference .js file in a typescript file when generating declaration file.
  • .ts, .tsx and .d.ts files take precedence over .js files when creating list of files for compilation
  • Project runner options cleanup
  • Project runner to accept tsconfig.json tests
  • Instead of consumeJsFiles option, support jsExtensions that allows user to specify comma separated list of extensions that are to be treated like javascript files
  • Bundle js files into --out and copy into --outDir

What's the difference between this and the built-in split ?

I could use split but then I would need to iterate over result again to make sure the strings are non empty and are correct.
