MapTypes

by Krzysztof "Wokay" Łokaj @wokayme

Implement `MapTypes` which will transform types in object T to different types defined by type R which has the following structure ```ts type StringToNumber = { mapFrom: string; // value of key which value is string mapTo: number; // will be transformed for number } ``` ## Examples: ```ts type StringToNumber = { mapFrom: string; mapTo: number;} MapTypes<{iWillBeANumberOneDay: string}, StringToNumber> // gives { iWillBeANumberOneDay: number; } ``` Be aware that user can provide a union of types: ```ts type StringToNumber = { mapFrom: string; mapTo: number;} type StringToDate = { mapFrom: string; mapTo: Date;} MapTypes<{iWillBeNumberOrDate: string}, StringToDate | StringToNumber> // gives { iWillBeNumberOrDate: number | Date; } ``` If the type doesn't exist in our map, leave it as it was: ```ts type StringToNumber = { mapFrom: string; mapTo: number;} MapTypes<{iWillBeANumberOneDay: string, iWillStayTheSame: Function}, StringToNumber> // // gives { iWillBeANumberOneDay: number, iWillStayTheSame: Function } ```
