Exploring the distinctions between types and classes through type hinting

It seems that I am facing some challenges with this task and the reason is unclear to me

switch (typeof request) {
    case 'EnrollmentRequest':

The type '"EnrollmentRequest"' cannot be compared to the type '"string" | "number" | "boolean" | "symbol" | "undefined" | "object" | "function"'

However, my goal is to

switch (typeof request) {
    case type(EnrollmentRequest):

so that I can receive type hints in PhpStorm

Answer №1

It seems that when dealing with a custom class, the typeof method will not work as expected. Instead, you should use the instanceof method. The error message clearly indicates that typeof can only be used with the types

'string' | 'number' | 'boolean' | 'symbol' | 'undefined' | 'object' | 'function'
.
