Daniel Rosenwasser 410b71751e Merge pull request #32034 from dragomirtitian/GH-32013-improve-error-messages-for-calling-types 
Improved error message for calling/constructing types
 2019-06-28 16:08:18 -07:00
Titian Cernicova-Dragomir e4bca9649a Improved error spans for call errors: 
1. When calling a non-callable expression the error span is on the call target not on the whole call
2. When calling a method, the error for overload resolution now includes the arguments (this was previously regressed by #31414)

Dhruv Rajvanshi ce23093a58 Merge branch 'master' of https://github.com/Microsoft/Typescript 2019-05-24 02:27:55 +05:30
Nathan Shively-Sanders 4d27361680 Allow JS with isolated modules (#31483) 
* Allow JS with isolated modules

Previously legacy JS code was not allowed; it was required to use ES6
module syntax. Unfortunately, the check happens after parsing but before
binding, and the commonjs module indicator isn't set until binding
because it's not syntactically simple like the ES6 module indicator,
which is set during parsing.

So I decided that JS should be allowed during isolatedModules
unconditionally. We're not going to be transforming it anyway.

* Update baselines

* Switch test to outDir instead of noEmit

Nathan Shively-Sanders b36c8a0690 Make anyArray.filter(Boolean) return any[], not unknown[] (#31515) 
* Add this-parameter workaround to Array.filter

Allows anys.filter(Boolean) to once again return any[], not unknown[].

* Add any constraint to Boolean factory function

I want to test how well this works.

* Remove Boolean factory type guard

* Remove typeGuardBoolean test
