tests/cases/conformance/es6/templates/taggedTemplateStringsTypeArgumentInferenceES6.ts(63,11): error TS2453: The type argument for type parameter 'T' cannot be inferred from the usage. Consider specifying the type arguments explicitly.
Type argument candidate 'string' is not a valid type argument because it is not a supertype of candidate 'number'.
tests/cases/conformance/es6/templates/taggedTemplateStringsTypeArgumentInferenceES6.ts(76,11): error TS2453: The type argument for type parameter 'T' cannot be inferred from the usage. Consider specifying the type arguments explicitly.
Type argument candidate '{ x: number; z: Date; }' is not a valid type argument because it is not a supertype of candidate '{ x: number; y: string; }'.
2015-01-20 23:18:22 +01:00
Property 'z' is missing in type '{ x: number; y: string; }'.
