Increment Operator

There are shortcut ways to do simple math on a variable. For instance, it is very common to add one to a variable, ie:

x=x+1; // this adds one to a variable

You can use a javascript shortcut to do the same thing:

x++; // two plusses also adds one to a variable

x—; // two minuses subtracts one from a variable (note there are two minus signs, notion.so shows it as a solid line)

There is also another shortcut that does the same thing:

x+=1; // this also adds one to a variable
