Q1: What does the following Regular Expression mean?(M31.FR10)

Summary_Q1
```JS
    // M31.FR10 define REGEX_QUOTED_TEXT: 
    // The pattern matches quoted texts like `"One quote"` or `"One quote" (Pg.1)`
    // Capturing Group (x) : Matches x and remembers the match.
    // Non-Capturing Group (?:x) : Matches "x" but does not remember the match. 
    // Quantifier +? : Matches the previous token between 
    //                 one and unlimited times, as few times as possible,
    //                 expanding as needed (lazy)
    // Modifier g : global. All matches (don't return after first match)
    // Modifier u : unicode. Enable all unicode features and  
    //              interpret all unicode escape sequences as such
    // #####################################################################
    // CASE_A:To match the quoted texts like "One quote"
    // Capturing Group (x) + non-greedy y+?
    // const REGEX_QUOTED_TEXT = /(".+?")/gu;

    const REGEX_QUOTED_TEXT = /(?:".+?")(?:\s\(Pg\.[0-9]+?\))?/gu; 
    
```

A1:

Non-Capturing Group (?:x) + non-greedy y+?
  • Non-Capturing Group (?:".+?")
  • Non-Capturing Group (?:\s\(Pg\.[0-9]+?\))?
  • Global pattern flags
    • g modifier: global. All matches (don’t return after first match)
    • u modifier: unicode. Enable all unicode features and interpret all unicode escape sequences as such
