We can’t be sure whether a variable typed as Bird | Fish has a fly method. If the variable is really a Fish at runtime, then calling pet.fly() will fail. 代码语言:javascript 代码运行次数:0 运行 AI代码解释 interface Bird { fly(): void; layEggs(): void; } interface Fish { swim...
For example, let’s imagine acreateStreetLightfunction that takes a list of color names, along with an optional default color. Copy functioncreateStreetLight<Cextendsstring>(colors: C[], defaultColor?: C) {// ...}createStreetLight(["red","yellow","green"],"red"); What happens when we...

Will use import type {} rather than import {} when importing only types. This gives compatibility with TypeScript's "importsNotUsedAsValues": "error" option addTypename (boolean, defaultValue:false) Adds__typenameproperty to mock data
