Question: Rewrite the following async/await code without async/await. Instead of returning the new balance, assign it to a property balance. Your solution must be functionally similar, e.g. the destination balance can not be read until the current account balance is written. Specify all data types.

async transfer(dest: string, amount: number): Promise<number> {

let newBalance = await this.storage.get(this.account);

newBalance -= amount;

await this.storage.set(this.account, newBalance);

let destBalance = await this.storage.get(dest);

destBalance += amount;

await this.storage.set(dest, destBalance);

return newBalance;

}
