The GamepadButton.value property of the
GamepadButton interface returns a double value used to represent the
current state of analog buttons on many modern gamepads, such as the triggers.
The values are normalized to the range 0.0 — 1.0, with
0.0 representing a button that is not pressed, and 1.0 representing a
button that is fully pressed.

js
let gp = navigator.getGamepads()[0];
if (gp.buttons[0].value > 0) {
// respond to analog button being pressed in
}
Value
A double.
