Tag: fat arrows

The fat arrows (=>) are special function expressions that confuse even the smartest of developers. Most JavaScript professionals know that closure changes the meaning of this (@ in CoffeeScript).

There’s no reason to be afraid of fat arrows in CoffeeScript. They are time savers (and clarity achievers) when it comes to the nested functions and jQuery event handlers. When they are applied to class methods, the good rule of thumb is: use => when we need @ to be the object in which method is written; use-> when we need @ to be the object in which method is executed.
