How can I stop hoisting?
Some ways to avoid hoisting are:
- Use let or const — As explained above, using let or const instead of var would throw an exception and not let the program run, hence helping catch the issue earlier.
- Use function expressions instead of function declarations.
Technically, var , let and const are hoisted. … let and const are only declared during hoisting, not initialized. Accessing uninitialized variables result in ReferenceError . Prefer let over var , wherever possible to avoid the confusion arising due to hoisting.
