  Underscore - JavaScript library that provides a whole mess of useful functional programming. - Source: dev.to / 6 months ago

• JavaScript evolution: From Lodash and Underscore to vanilla

  Underscore was created by Jeremy Ashkenas (the creator of Backbone.js) in 2009 to provide a set of utility functions that JavaScript lacked at the time. It was also created to work with Backbone.js, but it slowly became a favorite among developers who needed utility functions that they could just call and get stuff done with without having to worry about the inner implementations and browser compatibility. - Source: dev.to / over 1 year ago

• KlongPy: High-Performance Array Programming in Python

  There was a step-change improvement for me when I tried expressing some JS patterns via `underscore.js` instead of procedurally: eg: http://underscorejs.org/#each Thinking of something as `each | map | filter | sum` is waaay less buggy than writing bespoke procedural code to do the same thing. No doubt there is a "cost" to it as well, but the _abstraction_ is valuable. Now, if there were a "compiler" which could... - Source: Hacker News / over 1 year ago

  Not too far behind is Underscore.js, another utility library that's all about enhancing your JavaScript mojo. Whether you're dealing with arrays, objects, or strings, Underscore has got something for you. It's like Lodash's sibling, offering similar functionalities but with its own flair. The choice between them is like picking between chocolate and vanilla - it really comes down to personal taste. - Source: dev.to / over 2 years ago

  I once made a very crude and simple TiddlyWiki work-alike I called "HulloWurld" https://github.com/calroc/HulloWurld It's 143 KB, but it includes copies of Knockout, Underscore, Zepto, and the "Marked" markdown parser... ¯\_(ツ)_/¯ ( Good stuff BTW: http://knockoutjs.com/ http://underscorejs.org/ https://zeptojs.com/ https://github.com/chjj/marked ) Probably the only interesting bit is the code to save the page:... - Source: Hacker News / about 4 years ago

• Underscore.js: create a map out of list of objects using a key found in the object

  I am using the excellent Underscore.js library. I have a specific task which I can do fine using JavaScript or jQuery but was wondering if there was some sort of abstraction avaialable in Underscore that I was missing out on. Source: about 4 years ago

• Is it possible to get the index you're sorting over in Underscore.js?

  I'm using the JS library Underscore and in particular using the _.each and _.sortby library calls. I'm wondering if there's any possible way to get the index of the value within the iterator delegate. Source: over 4 years ago

• Lenses and Partial-application - Going functional one step at a time

  The code illustrated in this post is not recommended for use in production but the concepts most certainly are. Libraries like lodash and underscope provide many tried and tested, production-ready functions, some from the FP camp, that can simplify your code and make it easier to create reusable code. - Source: dev.to / over 4 years ago

• [AskJS] TIL StackOverflow monkeypatches the String prototype across its various sites.

  Underscore, then Lodash are examples for JavaScript of how useful features can be developed in a third party library that influence adoption in the language standard. As an example, Lodash would have been an inspiration / push for the ES2019 flatMap and ~flatten~ flat Array methods, without having modified the global prototypes. Lodash's lazy evaluation is listed as an inspiration in the current iterator helpers... Source: over 4 years ago

• Open source maintainer pulls the plug on NPM packages colors and faker, now what

  It's both technical and cultural. Javascript is used on the front end. Front end devs obsess (or at least used to obsess) over download sized. So you'd have crazy stuff like custom builds of Underscore (https://underscorejs.org/) with just the functions you wanted. Think manual sandboxing, if that makes any sense. You could get a package of Underscore with just map, filter and reduceRight, if you wanted to. Now,... - Source: Hacker News / over 4 years ago

• The Frontend Hitchhiker's Guide: 3rd Party Code

  These are libraries that are small and focused on making a specific problem easier for the developer. Moment.js can make displaying time based data and perform various operations with it. Underscore adds a collection of functional programming primitives to JavaScript if that's your cup of tea. Lodash is similar in providing functions to make working with arrays, numbers objects easier. - Source: dev.to / about 5 years ago

• Lodash in 2021: Necessary or Obsolete?

  If you have a couple of years as a developer, you've probably used either Lodash or Underscore.js. These are two libraries that provide a bunch of utilities to manipulate data, particularly array and objects. - Source: dev.to / about 5 years ago

  Debouncing an input in JavaScript is a common technique to reduce the rate of execution of a function. If a user is typing inside an input and you execute a function on each change of that input (each letter typed) it can quickly lead to a lot of computation power being used on just that. The common technique is called debounced and it will delay the execution of the function listening to the input, only every X... - Source: dev.to / about 5 years ago
