js
const audioCtx = new AudioContext();
const oscillator = audioCtx.createOscillator();
const gainNode = audioCtx.createGain();
oscillator.connect(gainNode).connect(audioCtx.destination);
console.log(oscillator.numberOfInputs); // 0
console.log(gainNode.numberOfInputs); // 1
console.log(audioCtx.destination.numberOfInputs); // 1
