Function delay

delay(delayMs: number): Promise<void>
delay some milliseconds and then return valOrFunc

Sample:
```
await xaa.delay(500);
await xaa.delay(500, "Result");
await xaa.delay(500, () => "Result");
```
Parameters
- delayMs: number
  number milliseconds to delay
Returns Promise<void>
valOrFunc or its returned value if it's a function.
- Defined in src/index.ts:115
delay<T = void>(delayMs: number, valOrFunc: T): Promise<T>
delay some milliseconds and then return valOrFunc

Sample:
```
await xaa.delay(500);
await xaa.delay(500, "Result");
await xaa.delay(500, () => "Result");
```
Type Parameters
- T = void
Parameters
- delayMs: number
  number milliseconds to delay
- valOrFunc: T
  the value to return. If it's a function, call it to get the value. It can be an async function.
Returns Promise<T>
valOrFunc or its returned value if it's a function.
