Cheat sheets are amazingly handy quick reference resources that are time saving and educational, so we should probably all use them at one time or another.
For frontend development, cheat sheets are especially helpful as most of us cannot commit every snippet, tag, etc, to memory. Just like language, there are times our brains go blank and a word we are trying to bring to memory just won’t come – it doesn’t mean we don’t know it, just that we can’t think of it right now. Of course, cheat sheets for words failing us don’t exist unless they are called dictionaries! So even if you think you know your subject inside out, a few handy cheat sheets can still prove invaluable.

Frontend Cheat Sheets
GitHub user logeshpaul is putting together a list of frontend cheat sheets – so if there is one you need that didn’t make it into our list, you could pop over there and see if it has made it into this open source, curated list – or maybe you have created a cheat sheet that you would like to include in this list.
Cheat sheets, in my opinion, are often wrongly named – they should be reference sheets, as that is exactly what they are, but whatever we choose to call them, they are invaluable for speeding up workflow and as memory joggers.
