Example: AND operator

This example turns on LED 3 , 3, if LEDs 1 , 1 and 2 , 2 are both on:

if (led.point(1,1) && led.point(2,2)) {
   led.plot(3,3)
}

Example: Comparisons of numbers and strings

When you compare two Numbers, you get a Boolean value, such as the comparison x < 5 in the code below:

input.onButtonEvent(Button.A, input.buttonEventValue(ButtonEvent.Down), () => {
    let x = randint(0, 5)
    if(x < 5) {
    basic.showString("low");
    } else {
    basic.showString("high");
    }
})

See the documentation on Numbers for more information on comparing two Numbers.
