Function substring

Extracts a random substring from the provided content string.

Selects two random positions within the content and returns the substring between them. The starting position is always before the ending position. Automatically trims whitespace from the beginning and end of the result. Useful for creating excerpts, search terms, or partial content samples.

Example

  const text = "The quick brown fox jumps over the lazy dog";

  RandomGenerator.substring(text);  // "quick brown fox"
  RandomGenerator.substring(text);  // "jumps over"
  RandomGenerator.substring(text);  // "fox jumps over the lazy"

  // Generate search terms from content
  const searchQuery = RandomGenerator.substring(articleContent);

  // Create excerpts for previews
  const excerpt = RandomGenerator.substring(fullBlogPost);

  // Generate partial matches for testing search functionality
  const partialMatch = RandomGenerator.substring(productDescription);

  // Create random selections for highlight testing
  const selectedText = RandomGenerator.substring(documentContent);
