3 examples of using Async Generators and Async Iteration in JavaScript!
// Create a Promise that resolves after ms time
var timer = function(ms) {
return new Promise(resolve => {
setTimeout(resolve, ms);
});
};
// Repeatedly generate a number starting

Async Solidity Contracts

Having seen @pirapira's sketch of Bamboo ( https://github.com/pirapira/bamboo/ ), which proposed to add better control about the "smart contract program flow", even across calls, I thought that this should certainly be added to Solidity, and actually, it might even be possible now to a certain degree using inline assembly.

The problem is that with many functions in a contract, it is not always clear which can be called at which stage in the contract's lifetime. Certain smart contracts would be easier to understand if written as follows:

How to change your commit messages in Git?


At some point you’ll find yourself in a situation where you need edit a commit message.
That commit might already be pushed or not, be the most recent or burried below 10 other commits, but fear not, git has your back 🙂.


Not pushed + most recent commit:


git commit --amend


This will open your $EDITOR and let you change the message. Continue with your usual git push origin master.
