📰 Dev.to · Dev Nestio
Learn to build a text diff tool using the Myers algorithm in vanilla JavaScript, with 129 tests and no dependencies, to compare two blocks of text efficiently
Action Steps
- Implement the Myers algorithm in vanilla JavaScript to find the longest common subsequence between two blocks of text
- Write 129 tests to ensure the tool is working correctly and efficiently
- Use the tool to compare two blocks of text and highlight the differences
- Configure the tool to handle different types of text inputs, such as code or plain text
- Test the tool with various edge cases, such as empty strings or very large texts
