Also they return arrays, rather than just a single element as is the case with Array.shift. Both methods do the same thing only one directly modifies an array as Array.splice does, and the other returns a copy which is the case with Array.slice. So there is also the core js Array.slice, and splice methods that can be used to drop elements from the beging of an array, of any part of it actually. 3 - What about Array.splice, and Array.slice However there are other options in vanilla javaScript that might prove to be better vanilla javaScript alternatives so lets look at more examples when it comes to dropping some elements from the beginning of an array in JavaScript with and without mutating the source array. var text link Open main menuReferencesReferencesOverview Web TechnologyWeb technology reference for developersHTMLStructure content the webCSSCode used describe. Becuase it creates a new array rather than mutating the source array that is given it makes it a kind of functional programing method example sense the original array is not mutated in any way.īecause Array.shift mangles the original array it is not very functional like, and I can also only remove one element at a time as well, So then it does not quight do the same thing the say way as lodash drop then does it. Its a quick way to create a new array in which one or more elements are dropped from the beginning of the array.

In any case in this post I will be doing over some quick examples of the lodash drop method, as well as some plain old vanilla js alternatives. However I do not thing that the lodash drop method might be the best example of this. A lot of these methods do work differently, and provide a certain something that does go beyond what may be in the core of js itself, so yes maybe it is worth it. Sometimes it seems like I come across something like the _.drop method in lodash, and scratch my head wondering if looking into lodash is a wise investment of time or not. He wields the Sun Rod in his left hand and the Moon Rod in his right. On his metal limbs, he has black gloves and black shoes. He has large, reddish-orange eyes with green pupils. His upper body is rectangular with two thin arms sticking out of the sides. Still more often then not I tend to prefer to just work within core js by itself. Slice n' Splice is a light green, somewhat insect-like, four legged robot. So maybe some of these methods are not so redundant and there is also the question of backward compatibility as well when it comes to defending the use of lodash these days. There are also some methods that on the surface seem redundant but are actuality collection methods that will work with both arrays and objects in general. include a comment in the transformed file, that points to the source map. It looks like lodash is a bit of a mixed bag of methods some of which do not exist in javaScripts built in Array prototype, and other methods that appear to be redundant. A source map is a file that maps from the transformed source to the original source, enabling the browser to reconstruct the original source and present the reconstructed original in the debugger.
