TypeScript 2.1.4

Description

Erik Bivrin (CookieShade)
opened on Aug 5, 2016

TypeScript Version: 1.8.34

Code

letcanvas=document.createElement("canvas");letcontext=canvas.getContext("2d");letpattern: CanvasPattern=[];// !!!context.fillStyle=pattern;context.strokeStyle=0;// !!!

Expected behavior:
Fails to compile due to [] and 0 not being valid CanvasPatterns.

Actual behavior:
Successfully compiles, probably due to CanvasPattern being declared as an empty interface, which is obviously implemented by all objects. At runtime, the style is solid black.

                          opened on Aug 5, 2016
                          TypeScript Version: 1.8.34
                          Code
                          letcanvas=document.createElement("canvas");letcontext=canvas.getContext("2d");letpattern: CanvasPattern=[];// !!!context.fillStyle=pattern;context.strokeStyle=0;// !!!
                          Expected behavior:
                          
Fails to compile due to [] and 0 not being valid CanvasPatterns.
                          Actual behavior:
                          
Successfully compiles, probably due to CanvasPattern being declared as an empty interface, which is obviously implemented by all objects. At runtime, the style is solid black.
                          // lib.d.tsinterfaceCanvasPattern{}//...
fillStyle: string|CanvasGradient|CanvasPattern;//...
strokeStyle: string|CanvasGradient|CanvasPattern;
