console.log(“hi”) better than System.out.println(“hi”) or std::cout << “hi” at least

I don't think it's better than std::cout.

I think it is (because, well, think about what you would imagine if you don´tr know anything about C and JS. “Log ”hi“ into console” vs “cout ”hi“”)

These languages didn't get in on the “statements as expressions” idea, and as a result JavaScript doesn't have it, either.

Please elaborate on the “statements as expressions” part, I don't quite understand

In most languages, statements (such as if/else and switch) are used to select which code to run. But in newer and cooler languages, they can be used to return a value. One such language is Scala:

In Scala, the if/else statement can be used as an expression, so a separate ternary operator is not needed.

val b = true
val i = if (b) 3 else 2

But there are also cooler applications. For example, the “match” expression is like a cooler version of the “switch” statement. Just like the if/else expression, it can be used to return a value.

val i = 2
val j = i match {
  case 1 => "one"
  case 2 => "two"
  case _ => "many"
}

This is pretty neat because it prevents you from needing to write “j = ” a bunch of times, and from needing to declare the variable j separately from assigning it.
Another thing you can do is use blocks as expressions:

val f = 3;
val i = {val j = 2; j * f + 3} // We only use j to calculate i

Think of it as a very simple closure that has no arguments and returns the last expression.

Overall, the point of being able to use statements as expressions is to be able to write in a more expressive style, with less boilerplate and a clearer relationship between the different calculations involved.

It declares a variable.

NodeJS is generally regarded as very good for backend, probably better than Python. Here's how I would personally rate the 4 following backend languages (from best to worst):

C# (ASP.NET Core)
Node.js
Python
PHP

How about Go? (honestly though, C# for ASP.NET would not be the best universally, although it might be your favorite, because it isn't cross-platform. XD) Also, Java is used some (a huge pain though. XD), and Ruby has Rails and Sinatra, and I'm pretty sure Dart is used quite often for backend web dev too… Also TypeScript with Deno is another one to look out for, and ASP.NET can be done with VB too.

the point of programming isn't to be easy for beginners. imo python's simple syntax is what makes it so bad

Lambda is a concept I just don't get in javascript

Yea, cause python lambda is limited to one line

That's the point. Why use lambda when it's the same thing as just using “normal” functions?

gosoccerboy5 wrote:

…
then again, dart's lambda is superior above all, not even requiring the function keyword, or a clumsy =>

listOf(1, 2, 3, 4, 5).forEach {
    print(it)
}
 
val sum = { x: Int, y: Int -> x + y }
 
val product = items.fold(1) { acc, e -> acc * e }

if you ask me i will say both but if you have less time
i will say javascript but if you have more time i will say both
but i recommend java and C++(not javascript its “java” and javascritpt are different)
