A JS implementation of nested spintax

spintax.js

function processSpintax(text) {
  // Define the regex that captures the innermost { ... }
  const regex = /\{([^{}]+)\}/;

  // Keep going while the text still matches { ... }
  while (regex.test(text)) {
    text = text.replace(regex, (match, contents) => {
      // Split the contents by "|" 
      const parts = contents.split('|');
      
      // Choose a random part from the array
      return parts[Math.floor(Math.random() * parts.length)];
    });
  }

  return text;
}

note: nested is broken
