Using a Letter Shuffler in Cross-browser Testing
A string letter shuffler can be useful if you're doing cross-browser testing. For example, if you're writing tests for an algorithm that checks if a certain string can be created from another string of the same length but rearranged letters, then with this utility, you can create input and output tests cases. The input data for the test cases can be the original text and the output can be rearranged text, or the other way around. You can also remove some of the letters to make failing tests cases. Another use case, is rearranging letters to create random permutations of the given strings or text. For a string or a text fragment of length n, there are n! (n factorial) possible permutations of its letters (counting repeated letters). This program can also be used to obscure a short message. For example, if a website blocks certain words in the comments, then by slightly rearranging the letters you can get by this block. If you run such a website yourself, then it can also be helpful to test for inputs where short blocked words are tested for shuffled letters.
