Browserify is a powerful tool that lets developers use Node.js-style require() statements in browser-based JavaScript. This means you can organize your client-side code into modules and easily manage dependencies, just like you would on the server. Looking at versions 1.7.0 and 1.7.1, the core functionality remains the same, with both versions sharing identical dependencies like "nub," "resolve," "optimist," "commondir," "detective," and "coffee-script." The development dependencies, essential for testing and building the library, are also consistent, including tools like "seq," "tap," "jade," "dnode," "jsdom," "connect," "hashish," "backbone," "traverse," and "jquery-browserify."
The key difference between the two versions lies in the release date, with version 1.7.1 released shortly after 1.7.0. As a patch version increment (1.7.0 to 1.7.1), it likely contains minor bug fixes, performance improvements, or small adjustments that wouldn't significantly alter the API or overall functionality. The consistent dependency versions suggest stability and that the core build process remained unchanged. For developers already using Browserify 1.7.0, upgrading to 1.7.1 is generally recommended to benefit from the latest improvements and reduced risks thanks to bug fixes. You should always check official release notes or commit logs for detailed information on specific changes, but for most use-cases there should not be breaking changes.

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;");
