IMHO, this discussion got blown out of proportion quite a bit. It heavily optimizes for front-end CPU performance in a way that Underscore doesn't. ( source ) _.m , an alternative Objective-C port that tries to stick a little closer to the original Underscore.js API. This refers to the R-squared value of 0.95. It’s a bitch to cope with, to put it mildly. Do read the blog post earlier, and instead of believing it for its sake, judge for yourself by running the benchmarks. There are many ways to include a library: you can for example import, require or include in script tags.

For this, it uses both the total number of dependencies So Occam's razor tells us to use the simpler method. Lodash is a JavaScript library that works on the top of underscore.js. Underscore and Lodash (and similar libraries) are well documented and tested libraries that offer many useful functions not included in native JavaScript. Underscore.m, an Objective-C port of many of the Underscore.js functions, using a syntax that encourages chaining. Think about that when promoting …. But seriously, either name is fine by me. I would really appreciate if someone posted an article with a complete list of such differences. native equivalent is not supported. Because Lodash is updated more frequently than Underscore.js, a lodash underscore build is provided to ensure compatibility with the latest stable version of Underscore.js. the higher dependency churn indicates a desire to optimize one's dependencies together with an open mind for new ones.

Here’s the current state of it for posterity: In addition to John’s answer, and reading up on Lodash (which I had hitherto regarded as a “me-too” to Underscore.js), and seeing the performance tests, reading the source-code, and blog posts, the few points which make Lodash much superior to Underscore.js are these: If you look into Underscore.js’s source-code, you’ll see in the first few lines that Underscore.js falls-back on the native implementations of many functions. Fortunately, lodash.underscore.js preserves Underscore.js’s behaviour of copying everything, which for my situation was the desired behaviour. We can try to explore how the trends might continue by fitting Markov models to the data4. They currently hold first and ninth place, Embed. underscore has been out there for longer (since 7 years ago), it also has fewer open issues, more followers on Github and more forks.

There’s even a third solution. A new scientific truth does not triumph by convincing its opponents and making them see the light, alexa – How can I find echo dot’s MAC address without turning it off? it might predict for April and project 1 that the chance for Lodash is 0.3 and for Underscore is 0.7. javascript - underscore - ramda vs lodash . Lodash’s API is a superset of Underscore.js’s. Lodash is not winning by poaching Underscore projects. it will probably also include a utility belt. Share Copy … Generally, projects with many dependencies change their library portfolio more often of course. Choose whatever approach fits your needs the most. I’d prefer fallbacks on actual implementations over opinionated runtime cheats anytime, but even that seems to be a matter of taste nowadays. First of all, let's get an overview. Here we compare between axios, lodash and underscore. For comparison, these sizes are those I noticed with source-map-explorer after running Ionic serve: One can use BundlePhobia to check the current size of Lodash and Underscore.js.
