Function pick

Randomly selects a single element from an array.

Chooses one element at random from the provided array using uniform distribution. Each element has an equal probability of being selected. This is a convenience function equivalent to sampling with a count of 1, but returns the element directly rather than an array containing one element.

Example

  const colors = ['red', 'blue', 'green', 'yellow', 'purple'];
  const fruits = ['apple', 'banana', 'orange', 'grape', 'kiwi'];

  RandomGenerator.pick(colors);  // "blue"
  RandomGenerator.pick(fruits);  // "apple"

  // Select random configuration options
  const randomTheme = RandomGenerator.pick(['light', 'dark', 'auto']);
  const randomLocale = RandomGenerator.pick(['en', 'ko', 'ja', 'zh']);

  // Choose random test scenarios
  const testScenario = RandomGenerator.pick([
    'happy_path',
    'edge_case',
    'error_condition',
    'boundary_test'
  ]);

  // Random user role assignment
  const userRole = RandomGenerator.pick(['admin', 'user', 'moderator']);

  // Select random API endpoints for testing
  const endpoints = ['/users', '/posts', '/comments', '/categories'];
  const randomEndpoint = RandomGenerator.pick(endpoints);
