First restrict the second parameter to be the key value of the object, and then traverse the second parameter through the in operator to generate a new map type implementation. type TPick<T, K extends keyof T> = { [P in K]: T[P] } type PickRes = TPick<{ name?: 'aa', age?:...

I have close to zero experience with Babel's internals though. I would not be offended, if you think you can fix it yourself quicklier. Current Behavior Thetypescriptpreset is incompatible withd3-array/cumsum.js. The issue seems to only occur for arrow functions using the+=operator, nested...
