Browserify version 2.2.2 and 2.2.1 are both tools for enabling Node.js-style require() statements within browser-based JavaScript. They allow developers to modularize their front-end code, reusing existing Node.js modules or creating new, browser-compatible modules. Both versions boast identical core dependencies: through, duplexer, inherits, optimist, JSONStream, module-deps, browser-pack, syntax-error, browser-resolve, and insert-module-globals, insuring the primary functionalities of each version will be very similar. The development dependencies for testing and tooling also remained consistent, including seq, tap, dnode, mkdirp, and backbone.
The key difference lies in the release date, with version 2.2.2 released shortly after 2.2.1, suggesting a patch or minor update. Developers should choose the newer version (2.2.2) assuming it addresses potential bugs or minor improvements found in the previous iteration, this is especially true if version 2.2.1 is causing an issue. If both versions are working without issue, upgrading is a case by case choice. Given both are very old upgrading to a newer version may be something to consider if the developer is not constrained.
These versions, licensed under MIT and authored by James Halliday (substack), highlight the project's commitment to open-source principles and community contribution to front-end Javascript development. The differences may be minor, but using the latest stable release is a standard practice to ensure the best possible experience.

var genstr = function (len, chr) {
var result = "";
for (i=0; i<=len; i++) {
result = result + chr;
}
return result;
}
u.parse("var a = " + genstr(process.argv[2], "1") + ".1ee7;");
