Ah, syntax. Your logic might be sound but miss those commas, brackets, or a typo turns > into '<', and bam! broken code. But, hopefully, your JSlinter catches and corrects those some of those errors.
While your linter will catch incorrect use of for...in, how does one remember the use case for for...of or for...in? Which is for iterating over objects or through arrays/strings?
Remember the difference of for...in & for...of.
If you get shot and the bullet stays in your body, the doctor looks for the
foreign object.If a {bullet: "Full Metal Jacket"} is in a javascript ammo{} object, a developer looks
for...inobject. The pun/trick is pronouncingfor...inas “foreign.”
Do brush up on for..in usage as it doesn’t loop in an ordered fashion. This Bits of Code article explains well when to use for...in.
Other Memory Devices?
What tricks or methods do you use to remember syntax or bits of code?
