 ## Contributing features
 Features (things that add new or improved functionality to TypeScript) may be accepted, but will need to first be approved (marked as "Milestone == Community" by a TypeScript coordinator with the message "Approved") in the suggestion issue. Please include [feature] in the title of your forum post. Features with language design impact, or that are adequately satisfied with external tools, will not be accepted.
 
 Design changes will not be accepted at this time. If you have a design change proposal, please post it to the Language Specification forum.

 Compiler testcases generate baselines that track the emitted .js, the errors produced by the compiler, and the type of each expression in the file. Additionally, some testcases opt in to baselining the source map output.
