Play sound in JavaScript

Very simple function that plays sine wave in browser environment.

const play = (frequency = 300, duration = 1e3) => {
  const context = new AudioContext();
  const gainNode = context.createGain();
  const oscillator = context.createOscillator();
  oscillator.frequency.value = frequency;
  oscillator.connect(gainNode);
  gainNode.connect(context.destination);
  oscillator.start(0);
  setTimeout(() => oscillator.stop(), duration);
};

Just run play() or provide sine wave frequency or duration

play(8000, 1e3);
