💛 JavaScript tip ✌️ Many languages have a sleep, wait or delay function to pause the code execution during a given time, JS doesn't have it But, we can make our own version using a promise and setTimeout #JSTipsByRod #JavaScript #100DaysOfCode

💛 JavaScript tip ✌️ We can use Promise.race and setTimeout to add a timeout to any promise We simple execute our original promise inside Promise.race and also include another promise which will be rejected when a timeout is reached #JSTipsByRod #JavaScript #100DaysOfCode

#JavaScript tip 💡 Avoid writting async calls inside .map, .reduce, .filter, .forEach‼️ The order of the calls isn't respected instead use a traditional "for" block with awaits inside of it or "Promise.all" #JS #CodeNewbies #100DaysOfCode #coding #JSTipsByRod
