👑 Awesome one-liners you might find useful while coding. #javascript #codenewbie #100daysofcode #301DaysOfCode
What's the name of this color scheme.. looks sick! By the way awesome share!
My favourite one is to easily review an array of objects in a nice table format using `console.table`: var data = [{...},{...},{...},{...},{...},{...}]; console.table( data ); Example: github.com/palashmon/java…
This is cool for play, but always remember that code is for human consumption. Especially the use of lambdas in the second example gets confusing fast. @getify
Regarding your random color snippet, you might like `Math.random() * 0xFFFFFF`. Should be easier to remember :).
I recently realized passing just console.log as a callback will log each argument out, because console.log can take any number of arguments #javascript
Be careful with very big numbers and ~~ (in fact any bitwise operator) as they get converted to 32 bit which may not give you the expected output!
When I read one-liners I was ready for some js jokes!
when working with observables (rxjs) then is this very useful shortform: filter(Boolean). Thanks for the hint.
I was tinkering: combine 2 of these... const add5 = n => console.log({n}) || n + 5;
All of these seem to have been sourced from a two-week-old reddit post on r/javascript. It would be polite to attribute credit to the original authors ☺️ #javascript reddit.com/r/javascript/c…
I've probably spent hours bracketing arrow functions. Thank you!!
I didn't realise you could use none returning functions to do stuff with pipes, but I guess Javascript with evaluate console logging as falsy so it's valid, wow, this is why I love Javascript (but also equally hate it sometimes, especially when I forget zero evaluates as falsy)
afaik, random values include 0.0 but exclude 1.0 so you should multiply them by 16777216 (0x1000000)
Was really kind of hoping these were like Rodney Dangerfield style one liners. Couldn't make it work tho. Hey this is a rough crowd.
