How to check for duplicates in an array in the most time efficient way(JS)
1. Implement a password check. Essentially, evaluate if a string contains one uppercase, one lowercase, one digit, and one "special character". I had to ask for clarification on what a "special character" is here and was told anything that does not fall in the above. 2. Refactor a React component from the existing lifecycle methods into a functional component with hooks. This also came up multiple times in step 2, which was a bit of a yellow flag for me as they really honed in on this relatively simple problem. 3. Center a div inside its parent. 4. A tooltip is appearing inside a div, move it outside.
