* Fix type keyword completions 1. In functions, type keywords were omitted. 2. In All context, no keywords were omitted. (1) fixes #28737 (2) removes 17 keywords that should not be suggested, even at the toplevel of a typescript file: * private * protected * public * static * abstract * as * constructor * get * infer * is * namespace * require * set * type * from * global * of I don't know whether we have a bug tracking this or not. * Change keyword filter in filterGlobalCompletion Instead of changing FunctionLikeBodyKeywords * Add more tests cases * Make type-only completions after < more common Because isPossiblyTypeArgumentPosition doesn't give false positives now that it uses type information. |

TypeScript
TypeScript is a language for application-scale JavaScript. TypeScript adds optional types to JavaScript that support tools for large-scale JavaScript applications for any browser, for any host, on any OS. TypeScript compiles to readable, standards-based JavaScript. Try it out at the playground, and stay up to date via our blog and Twitter account.
Installing

Documentation
Building
In order to build the TypeScript compiler, ensure that you have Git and Node.js installed.
Clone a copy of the repo:
git clone https://github.com/Microsoft/TypeScript.git
Change to the TypeScript directory:
cd TypeScript
Install Gulp tools and dev dependencies:
npm install -g gulp
npm install
Use one of the following to build and test:
gulp local # Build the compiler into built/local
gulp clean # Delete the built compiler
gulp LKG # Replace the last known good with the built one.
# Bootstrapping step to be executed when the built compiler reaches a stable state.
gulp tests # Build the test infrastructure using the built compiler.
gulp runtests # Run tests using the built compiler and test infrastructure.
# You can override the host or specify a test for this command.
# Use --host=<hostName> or --tests=<testPath>.
gulp baseline-accept # This replaces the baseline test results with the results obtained from gulp runtests.
gulp lint # Runs tslint on the TypeScript source.
gulp help # List the above commands.
Usage
node built/local/tsc.js hello.ts
