void

void represents the return value of functions which don’t return a value. It’s the inferred type any time a function doesn’t have any return statements, or doesn’t return any explicit value from those return statements

In JavaScript, a function that doesn’t return any value will implicitly return the value undefined. However, void and undefined are not the same thing in TypeScript.
