TypeScript编译器已经禁止了许多此类操作。然而,有些操作还是有可能绕过编译器的,例如,使用as any转换对象的类型,或者在编译TS代码时关闭严格类型检查的配置,或者在代码中通过@ts-ignore忽略类型检查。 在ArkTS中,严格类型检查不是可配置项。ArkTS强制进行部分严格类型检查,并通过规范禁止使用any类型,禁止在代码中使用...
To override type errors that TypeScript may throw when casting, first cast tounknown, then to the target type. Example letx ='hello'; console.log(((x as unknown) as number).length);// x is not actually a number so this will return undefined ...
在ArkTS中,as关键字是类型转换的唯一语法,错误的类型转换会导致编译时错误或者运行时抛出ClassCastException异常。ArkTS不支持使用语法进行类型转换。 当需要将primitive类型(如number或boolean)转换成引用类型时,请使用new表达式。 TypeScript class Shape {} class Circle extends Shape { x: number = 5 } class Sq...
