Function return type trap in TS.

In TS there is a trap for function’s return type

function a {
    b();
}
function b {
    // some operations
    return typeC value
}

In the case above, the return type of function a would be void even though it finally returns value in typeC

To fix this problem, add a return before executing function b:

function a {
    return b();
}
function b {
    // some operations
    return typeC value
}
