Javascript Async/Await nachrüsten

Statt: web3.eth.getBlock(„latest“).then(console.log)

let getLatestBlock = async () => {
    return new Promise(function (resolve, reject) {
        web3.eth.getBlock('latest', function (error, result) {
            if (error) {
                reject(error)
            } else {
                resolve(result)
            }
        })
    })
}

//usage inside async function
let latestBlock = await getLatestBlock()
console.log(latestBlock)

Prominenteres Beispiel:

function timeout(ms) {
    return new Promise(resolve => setTimeout(resolve, ms));
}
