ordinary declare
declare function hello1(s: string):void;declare global
declare global {
function hello2(s: string):void
} declare any of the above in the declaration file xxx.d.ts , hello1/hello2,
can be detected and accessed globally, so what is the difference between the two declaration methods?
is mainly declare global how should I use it? I can"t find this usage in the official documents
https://www.typescriptlang.or.
Global augmentation, at the end
xxx.d.ts
xxx.ts
whether your file name is the same, change it to a different one. For example,
xxx.d.ts
yyy.ts
Global augmentations have the same behavior and limits as module augmentations.
Global declare is the same as declare
in the d.ts declaration file, any declare is global by default, so you can't have declare global in the d.ts file. Only the definition is in the module file. If you want global, use declare global
