Javascript Going Back Multiple Times In History

I know to go back in history with JavaScript you use: window.history.back(); But how can I go back multiple times. e.g. to go back 4 times I tried: window.history.back().back().ba

Solution 1:

i = number of pages you want to go back

window.history.go(-i) 

Solution 2:

Use history.go(-4). Source: MDN
