It has since become a superset of Underscore.js, providing more consistent API behavior, more features (like AMD support, deep clone, and deep merge), more thorough documentation and unit tests (tests which run in Node.js, RingoJS, Rhino, Narwhal, PhantomJS, and browsers), better overall performance and optimizations for large arrays/object iteration, and more flexibility with custom builds and template pre-compilation utilities. But that’s the premise, whether you like it or not. The Name: "Lodash" is cute, but keeping "Underscore" makes the most sense, both for historical and _ variable reasons. It's not very surprising that projects would migrate from Underscore to Lodash more often than the other way around. The fitted transition probabilities per month are shown here: This corresponds to a mix that appears stable, because its composition changes only slowly. Skip to content. I am stunned right now, seeing a Lodash performing 100-150% faster than Underscore.js in even simple, native functions such as Array.every in Chrome! Bearbeiten: Ich habe einen jsPerf-Test erstellt, um zu überprüfen, wie viel langsamer die Unterstrich-Lösung ist. I mean, I worked on projects where I had to address performance issues, but they were never solved or caused by neither Underscore.js nor Lodash. much of it got included into the language As nouns the difference between underbar and underscore is that underbar is a bar placed under a symbol while underscore is an underline; a line drawn or printed beneath text; the character. It was suggested for converting WP Core to lodash, jscodeshift could be leveraged. So programmers might not need to import the packages anymore. The first and most important thing is speed. Do read the blog post earlier, and instead of believing it for its sake, judge for yourself by running the benchmarks. As if “simple loops” and “vanilla Javascript” are more native than Array or Object method implementations. So let's use the model to predict where an individual project ends up after 2 years from just the starting state. Read their (. Module Formats. This one saved me a lot of time in the development of my project. As usual. For accurate results, please disable Firebug before running the tests. Quoting the aforementioned blog post: Most JavaScript utility libraries, such as Underscore, Valentine, and But jsPerf revealed an interesting Maybe all of you are working on large scale projects that need twitterish performance so that you really see the difference between 850,000 (Underscore.js) vs. 2,500,000 (Lodash) iterations over a list per second right now! In some cases this results in missing data — Generally, projects with many dependencies change their library portfolio more often of course. The following QL query will check whether a project depends on Lodash or Underscore: I've looked at the dependencies of JavaScript projects from June 2015 to July 2017.I've included all project… The converse is even rarer: Are they abandoning the utility belts or are they depending on them more and more? I believe that it’s better to prefer a code whose performance is more consistent across browsers. It provides everything that Underscore does, along with a few additional helper functions. On the basis of individual projects, And even a quick Google search indicates that this direction seems to be the more popular. Use Lodash if you’re into convenience and like its extended feature catalogue (deep copy, etc.) However, when you are targeting modern browsers, you may find out that there are many methods which are already supported natively thanks to ECMAScript5 [ES5] and ECMAScript2015 [ES6].
