Fake typing animation with async/await
async function nextFrame() {
return new Promise((resolve) => {
requestAnimationFrame(resolve)
})
}
async function randomDelay(min, max) {
const delay = Math.random() * (max - min) + min;
const startTime = performance.now()
while (performance.now() - startTime < delay) {
await nextFrame()
}
}
async function simulateTyping({string, target, min = 10, max = 80}) {
for (const letter of string) {
target.insertAdjacentText("beforeend", letter)
await randomDelay(min, max)
}
}

// Example

simulateTyping({
  string: "hello world",
  target: document.querySelector(".fake-input"),
}).then(() => console.log("done"))
