Feb 4, 2015 at 9:26 comment added Claudia With regards to the instance methods allowing mutability, I was specifically addressing this: "Note that if you want to change the same array that you are mapping over, it will fail."
Feb 4, 2015 at 9:19 comment added Optimizer @impinball oh yeah. While that is true, the purpose of that example is to show the usage of , and how to club multiple statements. I just chose map randomly.
Feb 4, 2015 at 9:19 comment added Claudia @Optimizer The Array prototype methods. map, filter, reduce, forEach, every, some, etc.
Feb 4, 2015 at 9:18 comment added Claudia (a=b,a.map(d)) can be further shortened to (a=b).map(d), because the assignment returns the original value.
Feb 4, 2015 at 9:16 comment added Optimizer @impinball which instance methods ?
Feb 4, 2015 at 9:14 comment added Claudia You can modify the original array with the instance methods. The second is the current index, and the third is the array being iterated.
