Added console clearing with a message to --watch starts#20427

Conversation
I advocated against immediately clearing the console when starting --watch in microsoft#17756 because it was confusing to have the console suddenly become blank, wait a while, and _then_ give output. After using the feature for a little while, I think it's a little disorienting how the console will only start clearing after the first recompile. This change clears the console and immediately prints a new "Starting compilation in watch mode..." message.

There was a problem hiding this comment.
Can you create function expression clearScreen when entering this function and use that instead of if checks here and in update program?
const clearScreen = watchingHost.system.clearScreen ? watchingHost.system.clearScreen.bind(watchingHost.system) : noop;

Is it possible to still have the old behavior behind the flag? |
