Like any low and no code IDE, Wappler has a learning curve. What web development skills you brought with you when you started using Wappler may shorten that curve, but it's still steep initially.
My tip here, is a lesson I just learned myself: revisit the code on the early Wappler pages you built when starting to use Wappler. You are certain to have made mistakes you no longer make. You are certain to have implemented Wappler components that are less efficient than your ability today. And you are certain to have developed a familiarity with more Wappler components along your learning curve than you had initially.
Take some time and look through the pages you built in the first few months. For me, it meant resolving an issue that eluded me for over 6 months!
