The _.cloneDeep() method is used to create a deep copy of the value i.e. You can use import and export in modules.Let’s talk about export first. It has the capability for "lodash chaining" that will execute things at O(n), as opposed to O(Xn) depending on what you want... so, _(Game.rooms).filter(r->r.terminal && r.terminal.my).map(r=>r.terminal).values() would be O(n) where n = Object.keys(Game.rooms).length. @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.

The lodash and UnderScore both are utility libraries from JavaScript which helps make it easier by providing utils which makes, working with arrays, numbers, objects, and strings much easier. We particularly like the ES6 version of Lodash, where we can import the method names directly, without resorting to * or _ syntax. lodash vs Polly.JS: What are the differences? No packages published . Maybe you shouldn’t, especially if you’ve already loaded Lodash or some other utility library. The table shows the the individual lodash.utility packages are smaller until the number of packages rises. Also, for the beginners reading these things and using it to decide on native vs lodash... stop right now. We got hooked on the 'get' function to defensively pluck fields from objects without crashing our user interface, and have found countless uses for the other lodash functions throughout our apps. so instead of doing Object.values(Game.rooms) to turn it into an array before using ES6 array prototypal functions, you can just use straight lodash functions. Once we hit the 10 utilities mark, lodash-es pulls ahead in smallest bundle size. An ES6 module is a file containing JS code. Lodash also handles both overloaded signatures, and to do so, lodash puts all the arguments into an array, and flattens it. (besides the checks that u/quenoz mentioned), Also keep in mind that the lodash Version in screeps is quite old... so it‘s not optimized for newer versions of node. On the other hand, the existence of a pure ES6 solution does not mean that you are not allowed to use lodash’s variants. The performance difference you see here is almost always irrelevant in most applications. But Lodash’s _.map is more powerful, in that it works on objects, has iteratee / predicate shorthands, lazy evaluation, guards against null parameter, and has better performance..

Why you should embrace lodash. lodash vs es6 (intersection) (version: 0) Comparing performance of: lodash vs es6 Created: 20 hours ago by: Guest Jump to the latest result. If you just stuck with ES6, Object.values(Game.rooms).filter(r->r.terminal && r.terminal.my).map(r=>r.terminal) would be O(2n)+O(m) where n = Objecy.keys(Game.rooms).length and m = # of your terminals. If we’re using a modern browser, we can also use find, some, every and reduceRighttoo. To my knowledge screeps supports es6 so is there any reason to use lodash over built in es6 functions for things like filtering, foreach, map, ect? Test case created by on 2013-12-18 and last updated on 2013-12-19. So when reading tutorials, guides, and most code I've seen online, nearly all of it uses lodash.

These collection methods make transforming data a breeze and with near universal support. There’s no special module keyword; a module mostly reads just like a script. Java applet disabled. The Lodash command-line interface is available when lodash-cli is installed as a global package: Cole Turner: Worth noting that objects don’t guarantee sort order, and stringify is going to cost more in performance because it has to serialize the whole object whereas lodash can exit early if it finds a mismatched key. Map/Reduce/Filter/Find Vs For loop Vs For each Vs Lodash vs Ramda - dg92/Performance-Analysis-JS. Lazy, on the other hand, should potentially offer even better performance, at the cost of implementing a slightly different API. For the reason of curiosity, an experiment is made, by handling 10000 objects array, on both method, to see the different of between them by time, CPU and RAM. This library has helped everyone in my organisation complete tasks at faster pace as per the requirement. For accurate results, please disable Firebug before running the tests. Syntax: _.cloneDeep( value ) Parameters: This method accepts single parameter as mentioned above and described below: value: This parameter holds the value that need to be clone recursively. The advantages of the Set approach are twofold. They have mentioned working on a "multiple runtimes" version of the game, where ppl could choose a "flavor" of screeps to run their code, including a lodash 4.x version, or where Creep and PowerCreep inherit from a parent class, neither of which is available to us now.
