My Journey to Learning Javascript: Notes- Increment / decrement operators

Math operators can be used to used to increment or decrement value.

This is used to increment by one (++) and ( — ) is used to decrement by one. These two variables are the same.

var newVariable = myVariable++;

var newVariable = myVariable+1;

var newVariable = myVariable- -;

var newVariable = myVariable-1;

You could also decide how much you would like to increment or decrement. by using (+=) or (-=) followed by a number.

var myVariable+= 10;

Var myVariable-= 10;

Order of operations also apply in javascript.
