JavaScript Tutorial For Beginners #9 – Math Operator Short-hand

111.2K views on YouTube

Hey guys. In this JavaScript tutorial I want to build on what we’ve already learnt about mathematical operators, and show you a few cool short-hand notation versions that will save you time.

+= is the short-hand for adding to the current variable

-= is the short-hand for subtracting from the current variable

*= is the short-hand for multiplying by the current variable

/= is the short-hand for dividing the current variable

++var or var++ are the incremental operators (increase the value of the variable by 1).

–var or var– are the decremental operators (decrease the value of the variable by 1).

As usual, comment down below with any questions :).
