P42 Library Modernization
"I enjoy using the latest JavaScript features - it makes me more productive. However, keeping large codebases up-to-date with ever-evolving specifications used to be challenging and tedious. P42 solves this problem for me by automatically modernizing projects with its refactorings! Now I can be more productive without refactoring my code by hand. Such a time saver!"
