JavaScript shorthand tips and tricks | d'bug
“There is no official ECMAScript or JavaScript language feature called “shorthand”. Developers are responsible for coining the phrase, probably after realizing that terms like Ternary Condition are a bit archaic. The Mozilla Core JavaScript Guide does an excellent job of highlighting many of these shorthand techniques throughout tutorials, but I thought it best to have a definitive list all in one place. If you have others you would like to add, please feel free to comment.
“Boolean shorthand is probably most overlooked by beginners. It is a clean approach, even if you do not get a major decrease in file size. One thing to remember is that the exclamation point questions whether a value is false, not if the current value is the opposite of the initial variable value. This is a common mistake.”
