RegExp.escape(string)

Computes a new version of a String value in which certain characters have been escaped, so that the regular expression engine will interpret any metacharacters that it may contain as character literals.

When the escape function is called with one argument string, the following steps are taken:

  1. Let string be ToString(string).
  2. ReturnIfAbrupt(string).
  3. Let length be the number of characters in string.
  4. Let R be the empty string.

Workout Difficulty & Benchmark Estimation Heuristics

Key Factors Considered

  • Workout Format:
    • Monostructural (run, row, bike): difficulty primarily based on distance/time domain; benchmarks well-established (e.g., 5k run, 2k row)
    • Couplets/Triplets: difficulty depends on load, skill, and volume
    • Chippers/Pyramids: longer duration, high volume, often higher difficulty
    • AMRAPs: difficulty varies widely; depends on movement mix, duration, and skill
  • Max load: difficulty based on % of Rx

1. Input WOD Data (from jq output):

  • WOD Name: Frelen

  • Description:

    5 Rounds for Time
    800 meter Run

15 Dumbbell Thrusters (45/35 lb)

Okay, I will analyze the provided WOD, determine its difficulty and difficulty explanation using the heuristics from src/memory-bank/systemPatterns.md, and then derive the re-evaluated band ranges with explanations.

WOD Details:

6 ROUNDS for time:

  • 400m Run
  • 5 Bar Muscle Ups
  • 10 Alternating DB Power Snatch (50/35 lbs)
  • 400m Run

The user wants the overlay to cover the entire dialog without internal padding and ensure the dialog's close button (if one exists and is part of the dialog structure itself, not the form) remains functional and not covered.

The LogScoreForm is typically rendered inside a dialog/modal. The current implementation places the overlay inside the LogScoreForm's main Box wrapper.

// LogScoreForm.tsx
export const LogScoreForm: React.FC<LogScoreFormProps> = ({...}) => {
  // ...
  return (
  {/* Overlay is child of this Box */}
var HAS_EXPANDING_BOX_BUG = (function(){
var el = document.createElement('div'),
isBuggy = false;
el.style.width = '1px';
el.innerHTML = 'xxxxxxxxxx';
document.body.appendChild(el);
isBuggy = (el.offsetWidth > 1);
document.body.removeChild(el);
el = null;
return isBuggy;
