difference between npm run and nmp start? : <p>we have a lot of ts code which we can compile and run via "npm run dev".  This allows us to hit the test js code via localhost.  however, in the chrome debugger, 90% of the code is not visible (anonymous), and code which is not is too generic (such as find) to figure out how the thing which the debugger is showing as being slow or called a lot relates to our source code.</p>
