It allows us to type cast when declaring variables which means we explicitly set the type of data we expect back. Then it throws errors if the returned data is not the type we expected to get back, or if a function call has too few or too many arguments. And that's just a sampling...

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...
