JavaScript

const increment = (number, value=1) => number + value || number+1;

                          <<<  `|| number+1;`  >>>

the code work but it wrong

Set Default Parameters for Your FunctionsPassed (js)

What do you think this code should do? Use of the || operator in this way can be tricky and it might not do what you expect.

the challenge it says

Why did you add the OR? Are you just trying to find a way to break the tests and provide a slightly broken answer that passes the test suite?

The correct way is what you wrote but with the OR removed. The purpose of this challenge is practicing setting default values for function parameters.

it is 6, but not becouse of the || number+1 part
it is 6 because of the default parameter, this:
