A handy little debugging trick you can use in javascript is throwing exceptions to provide descriptive error messages in the console. throw new Error('hello world') ? You can take this one step further by throwing a variable directly (works with all datatypes) #javascript #js https://t.co/BLm2L6A4Qp

??? Tip: awaiting is an execution-blocking operation, as in the rest of the function won't execute until the awaited promise is resolved. Run promises concurrently by awaiting references to the already executed promises! (You can also do this with Promise.all()) https://t.co/Vp1C6pOXkJ

Here's a #javascript tip that I use every single day! Instead of: console.log('car', car); console.log('book', book); console.log('value', value); You can do: console.log({car, books, value}); ? https://t.co/EusxwK9iW7

JavaScript Teacher @js_tut
Type in Chrome console: const obj = { } Then type: copy( obj ); Result: const obj = { } will be copied to clipboard. Paste it into your text editor. Works with any currently defined object. Makes debugging a lot easier – used it 1000+ times @ work.

? 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
