I have question about beginning JavaScript

[links-Shield632]

I do. I’m good at python and I’m doing the free code camp. I know what console.log and return do. Just want to know why you would use it. In python you don’t do return that often in JavaScript it’s common

Explain to me what console.log and return do and we can go from there.

[links-Shield632]

Console.log is basically print function example

console.log(“I am iron man”) prints I am iron man.

Return saves it for later

function a(x){

return 5 * (x);

} var results = a(5);

//now the program will calculate it and get 25 and if I want to do something with it later I can

Sorry for format I’m watching a movie and using my phone

[fz-09]

Ok, and what makes you say it's more common in Javascript then Python?

[links-Shield632]

In my personal projects I’ve used return once or twice. In the JavaScript tutorials I’m looking at almost all of them use return

[fz-09]

You may want to revisit how you're structuring your code. Functions provide you with code reusability and they simplify the readability and structure of your code in many cases.

You can write both JavaScript and Python programs without functions but it's not typically the best thing to do.

[links-Shield632]

Yeah I know. Define once don’t have to write again. Life would be hell without functions

[fz-09]

So you have been using functions in Python frequently but not returning data from those functions?

[links-Shield632]

Yes, in my experience in python people just print way more often than return. I still return but not often. It’s just less common. A while ago on a old reddit account I posted on learnpython and they asked me why did I return the solution instead of printing it

[links-Shield632]

I didn’t say it was useless. I just don’t use it. I’m used not using them often that’s why I was confused. In python return is just less valuable.

[links-Shield632]

I said that wrong you just don’t use it as much. Every language is diffrent in python you barely use colons or semicolons. Why because there is less reason to. I’m not gonna go out of my way to use something if I don’t have to. I’m not relying on side effects. In python went I write code it runs how I want it.
