* Update LKG
* Update version
* Update LKG
* Skip overloads with too-short function parameters
If the parameter of an overload is a function and the argument is also a
function, skip the overload if the parameter has fewer arguments than
the argument does. That overload cannot possibly apply, and should not
participate in, for example, contextual typing.
Example:
```ts
interface I {
(a: number): void;
(b: string, c): void;
}
declare function f(i: I): void;
f((x, y) => {});
```
This code now skips the first overload instead of considering.
This was a longstanding bug but was only uncovered now that more
functions expressions are context sensitive.
* Test skip overloads w/too-short function params
1. Update changed baseline.
2. Add a new test with baseline.
* Minor style improvements
* Ignore optionality when skipping overloads
* Do not use contextual signatures with too few parameters

TypeScript
TypeScript is a language for application-scale JavaScript. TypeScript adds optional types, classes, and modules to JavaScript. TypeScript supports 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
For the latest stable version:
npm install -g typescript
For our nightly builds:
npm install -g typescript@next
Contribute
There are many ways to contribute to TypeScript.
- Submit bugs and help us verify fixes as they are checked in.
- Review the source code changes.
- Engage with other TypeScript users and developers on StackOverflow.
- Join the #typescript discussion on Twitter.
- Contribute bug fixes.
- Read the language specification (docx, pdf, md).

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 runtests-browser # Runs the tests using the built run.js file. Syntax is gulp runtests. Optional
parameters 'host=', 'tests=[regex], reporter=[list|spec|json|<more>]'.
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
