In this JavaScript tutorial, we look at How to Practice Good Scoping in JavaScript, Practicing Good Scope on Codecademy, Learning to Code. In this walkthrough from the Scope section, we take on the lesson, ‘Practice Good Scoping’. In it, we dive deeper into scope and good practice when declaring variables. We are taught that tightly scoping our variables help improve our code in many ways! We learn that it will make our code more legible and understandable. Another important reason to practice good scoping is that it will save memory in our code since variables cease to exist after the block finishes running! Understanding Scope is key in understanding when variables can be accessed within your program. Master it before moving on for optimal Javascript and programming mastery!
