As a beginner in TypeScript, I am looking for help with the following code snippet:
async function sleep(ms: number) {
return new Promise((resolve, reject) => {
setTimeout(() => resolve(), ms)
})
}
async function randomDelay() {
const randomTime = Math.round(Math.random() * 1000)
return sleep(randomTime)
}
class ShipmentSearchIndex {
async updateShipment(id: string, shipmentData: any) {
const startTime = new Date()
await randomDelay()
const endTime = new Date()
console.log(`update ${id}@${
startTime.toISOString()
} finished@${
endTime.toISOString()
}`
)
return { startTime, endTime }
}
}
// Now, I need to write a class that implements the ShipmentUpdateListenerInterface. How can I achieve this in TypeScript?
