String to color converter

stringToColor.js

function stringToColor(str) {
  // Predefined set of colors
  const colors = ['#FF5733', '#33FF57', '#3357FF', '#F833FF', '#FF8333', '#33FFF8'];
  
  // Simple hash function
  let hash = 0;
  for (let i = 0; i < str.length; i++) {
    const char = str.charCodeAt(i);
    hash = ((hash << 5) - hash) + char;
    hash = hash & hash; // Convert to 32bit integer
  }
  
  // Ensure the hash is a positive number
  hash = Math.abs(hash);
  
  // Map the hash to one of the predefined colors
  const colorIndex = hash % colors.length;
  return colors[colorIndex];
}

// Example usage
console.log(stringToColor("hello")); // One color
console.log(stringToColor("world")); // Consistently returns the same color for "world"
console.log(stringToColor("world")); // Consistently returns the same color for "world"
console.log(stringToColor("hello world")); // Different string, different color
