"analogWrite" vs "digitalWrite"

What is the difference between analogWrite() and digitalWrite()? I will show two different blocks of code that gave me the exact same output on my hardware. There are the codes;

int led=1, brightness=255;
pinmode (led, brighness);
digitalwrite(led, brightness);

and

int led=1;
pinmode(led, output);
digitalwrite(led, high);

When I write these codes I can change digital to analog and get the exact same results. Why is this? What is the difference? Is one preferable over the other?

and yes i know that half the code is missing and that there are no caps, but you should be able to understand what I'm trying to say.

Pin 1 is not a PWM pin (3, 5, 6, 9, 10, and 11 are on the UNO). For a non-PWM pin, analogWrite() with a value below 128 is tha same a digitalWrite(LOW) and analogWrite() with a value above 127 is tha same a digitalWrite(HIGH).

You don't need pinMode() for PWM pins. The analogWrite() function takes care of that.

The PWM value 255 is full brightness. You won't see a difference between that and digitalWrite(HIGH).

The PWM value 255 is full brightness.

That depends how the LED is wired.
