Can't push, what should I do?

Question

git

Hello, there was a problem with push, when I enter this command
git push -u origin master
This pops up:

To https://github.com/ratatyq/ShooterMiniGame.git
 ! [rejected]        master -> master (non-fast-forward)
error: failed to push some refs to 'https://github.com/ratatyq/ShooterMiniGame.git'
hint: Updates were rejected because the tip of your current branch is behind
hint: its remote counterpart. Integrate the remote changes (e.g.
hint: 'git pull ...') before pushing again.
hint: See the 'Note about fast-forwards' in 'git push --help' for details.

Answer 1

The actual answer to the question is 'git pull ...') before pushing again.

Answer 2

var
  path = 'aaa.bbb.ccc.ddd',
  data = {
    aaa: {
      bbb: {
        ccc: {
          ddd: 'Hello!!'
        }
      }
    }
  };

console.log(path.split('.').reduce((p, c) => p[c], data)); // Hello!!

Answer 3

We are writing a function that will iterate over the object and, if the value of the object's key takes on the object, calls itself, and so on until it finds the desired key. https://learn.javascript.ru/recursion
