someArray.sort((a,b) => a - b);

Edit: I'm actually truly grateful, I'm sure this bit of knowledge saved me some of my hair in the future.

ikewise, I felt a little let down. On the flipside, it's an excellent opportunity to bring Rosetta Code to people's attention - a wiki with hundreds of example problems, each solved in many languages for comparison!

https://www.rosettacode.org/wiki/Rosetta_Code

I find it invaluable in that sort of mid-learning level of a new language, where I have the syntax sorted, but I need lots of programs small enough to hold in my head, but also large enough to show off all the features, to learn and read. Here's Dijkstra, for example: https://www.rosettacode.org/wiki/Dijkstra%27s_algorithm

Common Lisp: https://github.com/sharplispers/clx

Go: https://github.com/BurntSushi/xgb

Any others?

(Looking for implementations of the X11 protocol in $LANGUAGE, not bindings to the C Xlib)

Now I'm kind of glad you responded in kind because I'd seen python-xlib but not the node one. That sounds like a bit of fun and punishment at the same time.

Although this is a case where idiomatic python is different from idiomatic js.

In js:

  // same:
  !! ""   // false
  !! 0    // false
  !! 1    // true
  !! null // false  

  // different:
  !! {}  // true
  !! []  // true

  # same:
  not not ""    # False
  not not 0     # False
  not not 1     # True
  not not None  # False
  
  # different:
  not not {}       # False
  not not []       # False
  not not tuple()  # False

Perhabs just personal preference but I'd use

    for(let element of someList){
    	console.log(element);
    }

    someList.forEach(element => {
      console.log(element)
    })

    Object.entries(newDict).forEach(element => {
      console.log(`${element[0]} ${element[1]}`)
    })

    for (const key in newDict) {
      console.log(`${key} ${newDict[key]}`)
    }

    for (const [key, value] of Object.entries(newDict)) {
      console.log(`${key} ${value}`)
    }

Second: I don't like seeing JavaScript code without semicolons. Maybe I am old, but it makes me nervous.
