Filter: Rewrite double negative
See original GitHub issueChallenge Filter Arrays with filter has an issue.
The intro sentence uses a double negative:
The filter method is used to iterate through an array and filter out elements where a given condition is not true.
I suggest re-writing in the positive because it’s easier to read and understand. Also, it’s how I happen to think of filter, and maybe others do too. Here I made that change, plus removed “filter” from its own definition, and changed it from passive to active voice:
The filter method iterates through an array and selects elements where a given condition is true.

@dogweather I would amenable to this change.
@FreeCodeCamp/issue-moderators second opinions?
“The filter method is used to create a new array by iterating through the array it is called upon and keeping only elements where a given condition returns true.”
I think it’s important to know that .filter() makes a new array.
