Can someone explain what promt is in the code and its meaning?

Question

// if-else if
var age = prompt ("Please enter your age.");
if (age <= 12) {
document.write("You are a child.");
}
else if (age <= 18) {
document.write("You are a teenager.")

}
else if (age > 18) {
document.write("You are getting old.")
}
else {
document.write("You did not enter an age.")
}

Answer 1

prompt asks for an input.
It 'promts' you for input.
