lodash sortby descend

To read more about the library, explore the methods see the Lodash documentation. The _.sortBy() method creates an array of elements which is sorted in ascending order by the results of running each element in a collection through each iteratee. Lodash library is one of the best free open source utility libraries that allows us to do the same on the client side. Lodash works great with Node.js. I recommend GitHub: Array sortBy – a best implementation of sortBy method which uses the Schwartzian transform. You can also specify the option in either of the following forms: Lodash is a JavaScript library that works on the top of underscore.js. In native javaScript there is the array sort method that can also be used when it comes to not using lodash as part of a … Here are two main issues. Example 1.3.0. Lodash helps in working with arrays, collection, strings, objects, numbers etc. Arguments. Questions: There’s a nifty method to sort an array of object based on several propertes: var data = _.sortBy(array_of_objects, ['type', 'name']); However that is only for ascending sorting. We’ll look at two scenarios using features such as find and reduce. I used the Lodash docs to create the solution below however .orderBy doesn't seem to be having any affect at all. Speed. It can handle robust data manipulations with ease. compose is often the classic tool for people coming from an FP background as it reads in the same way as the manual composition, but flow reads sequentially left to right and is, therefore, the first choice of all other people. We are using it in an Angular 2 application. The first and most important thing is speed. Yeah tbh it's slightly hidden in the documentation itself, but the relevant documentation is here.There's a big paragraph there that discusses the difference between _(foo) and _.chain(foo), but the main point is you get an object that lets you chain the usual lodash methods and call .value() when you want the final result.. Is there some handy way of defining direction per column? It also reads the same way as a promise chain. Taken from lodash’s documentation website. Creates a lodash wrapper instance that wraps value with explicit method chain sequences enabled. I am trying to sort an array by 'name' value (using Lodash). Returns (Object): Returns the new lodash wrapper instance. sortBy on an array containing both strings and numbers gives strange results: _.sortBy([6,5,4,"hi",3,2,1]) [1, 4, 5, 6, "hi", 2, 3] I think this happens because comparison between a number and a string will coerce the string into NaN, which is neither greater than nor less than any other number: Let’s create a method to sort arrays being able to arrange objects by some property. So the lodash order by method is another option on top of the lodash _.sortBy method whe it comes to sorting object collections in general both with arrays, and objects in general. The result of such sequences must be unwrapped with _#value. @qiansen1386 Can't comment on "Ramda vs Lodash" (I am familiar with Lodash, but not so much with Ramda), but in Haskell (FP beast) I see it is common to use fn composition and actually prefer it even thought there are possibilities (in std. value (*): The value to wrap. But for now we are going to try this approach Gist: sortBy-old.js. Since. E.g. And compare them with JavaScript analogues. _.orderBy(collection, [iteratees=[_.identity]], [orders]) This method is like _.sortBy except that it allows specifying the sort orders of the iteratees to sort by. library and beyond) to use reversed functional composition. If orders is unspecified, all values are sorted in ascending order. In light of this I tend to think it is just a matter of taste/habit which approach to use. Because performance really matters for a good user experience, and lodash is an outsider here. So why shouldn’t you use lodash?
