? If you are trying to debug something in the middle of chaining array methods, just map over it, console.log, and return it. Since console.log returns nothing, it will just pass the entire array through. You can even make a handle little debug function ? https://t.co/HCtLh4QYm6

TIL: `document.getElementsByClassName()` & Co return _live_ `NodeList`s. `document.querySelectorAll()` returns a _static_ `NodeList`. Use `querySelectorAll()`, people! https://t.co/s7aGuxMGgN

Hot tip ? Thanks to @wesbos and @stolinski for this gem I picked up from @syntaxfm. If you ever need to loop over an object in #javascript, take a look at the Object.entries method. So much more readable and so much less gnarly. https://t.co/xdY0Eg40cR

Nifty trick I've seen around and heard about on @syntaxfm - Array.from({ length: n }) gives you an array full of undefined that you can use in place of traditional for loops. Super handy for executing something a set number of times! https://t.co/AyUK8HtETe
Jeff Brown @jeffbrowndev
Thank you @wesbos & @stolinski! Here's a neat little trick I learned from these guys on @syntaxfm. Usally, I'll use Array.reduce( ) as a quick way to sum up an array of values. It's also a great way to keep a tally on values, such as words in a paragraph. Something like this: https://t.co/azJUZOv14Y

Skip Values in Destructuring ? You can use blanks to skip over unwanted values. This way you can avoid useless variable assignments for values you don’t want during destructuring ? #100DaysOfCode #CodeNewbie #301DaysOfCode https://t.co/dljom5lXNk
