"delay(10)" after Serial.begin in examples

[tttapa]

Many examples of the ESP8266WiFi library have this in the setup:

Serial.begin(115200);
delay(10);

What is the purpose of the delay? At first glance, everything seems to work perfectly fine without it.
GitHub search for "delay(10)"

Thanks,

this is maybe leftover from Arduino Leonardo examples

void setup() {
//Initialize serial and wait for port to open:
Serial.begin(9600);
while (!Serial) {
; // wait for serial port to connect. Needed for Leonardo only
}

// prints title with ending line break
Serial.println("ASCII Table ~ Character Map");
}

I usually use a 1 second delay so my serial program can reconnect to the serial port or else i miss the boot sequence and first print

a delay in the setup() won't give you time to see the boot message ...

sorry I meant my setup boot sequence, not esp

It's just left over code. It is not really needed nowadays.
It is used to give time for the esp to initialize the serial
