Using JavaScript hoisting to your advantage

Hoisting in JavaScript is a tricky technique, but when used correctly can be beneficial to your code. However, if misused it can turn a harmless looking declaration into a persistent issue. Hoisting is a mechanism where variables and function declarations are moved to the top of their scope before code execution. In this tutorial, Nairobi-based Andela developer Elizabeth Mabishi covers the following:


  • Basic overview of hoisting
  • How to hoist variables
  • Different hoisting functions
  • Order of precedence
  • Hoisting classes
  • Overall functionality


If you’ve ever wondered why you were able to call functions before you wrote them in your code, you’ve come to the right place! Check out the full tutorial here.
