"Got introduced recently to this library and I really like it."
4.5/5
What do you like best about Underscore.Js?

Tons of really helpful functions that make your coding quick and easy! Easy to understand and implement. Review collected by and hosted on G2.com.

What do you dislike about Underscore.Js?

It's not really an issue but the documentation page doesn't look very appealing. Me, as a frontend developer (mainly but I also do some backend sometimes) I want to see more color on a webpage. Not too much but just enough to make your eye not get bored :) Review collected by and hosted on G2.com.

"Functional programming at your hand"
4/5
What do you like best about Underscore.Js?

It is one of the most widely-known open source projects in the JavaScript programming world. The best functionality it features is the whole set of functional programming operations that gives a ton of power to the developer. Using Underscore allows the developer to get rid of some common but wearisome functionality chunks that otherwise they would need to code, test, and maintain themselves. Review collected by and hosted on G2.com.

What do you dislike about Underscore.Js?

In case you want to use Underscore in your project, you would need to include the whole library inside your project. That could impact performance when serving a web to your customer, in terms of waiting time. This problem has been successfully solved by other functional programming libraries, like Lodash. With Lodash, you can include in your code only what you really need. Also, in some parts of the library, it seems to be a bit outdated. It is an old library, released at the same time as Backbone.js, and you can tell that by looking at the documentation. It is very complete, but a bit chaotic when defining some functions.

"I'm a fullstack developer and sysadm and I develop internal admin tools. I work as a freelancer."
3.5/5
What do you like best about Underscore.Js?

I like the modular form of the framework and the multiple functions for resolving common problems when programming arrays, collections, and objects in the JavaScript language. Review collected by and hosted on G2.com.

What do you dislike about Underscore.Js?

I really don't like the syntax of chain functions; I find that putting the value function at the end of the line of code is verbose and ugly. Review collected by and hosted on G2.com.

"Solid, efficient tooling"
5/5
What do you like best about Underscore.Js?

Many times, I've found myself looking for the most efficient way to perform a process on data. In almost every case, Underscore.JS had a solution already in place. Review collected by and hosted on G2.com.

What do you dislike about Underscore.Js?

This product should have the capacity to deploy part of the tools, rather than the product, as a whole. Review collected by and hosted on G2.com.

"best utility library for JS users"
5/5
What do you like best about Underscore.Js?

how all the required utility functions are at once place, you import the library and you have it all Review collected by and hosted on G2.com.

What do you dislike about Underscore.Js?

It is so important and commonly used that probably it should be included or integrated with JS automatically Review collected by and hosted on G2.com.

"JavaScript utility belt which is both light weight and awesome"
4.5/5
What do you like best about Underscore.Js?

UnderscoreJs is pretty lightweight but packs some very useful methods for collection manipulations and templating in javascript. I used _.template() primarily for HTML templating and manipulating objects and collections. Methods like _.pluck and _.shuffle give powerful abstractions to filter arrays of objects without the need for heavy boilerplate code. The _.throttle and _.debounce methods come in handy when you need to throttle and control a burst of potentially repeated user inputs on a webpage. UnderscoreJs is also available on NodeJs platform as a managed dependency via npm registry. Review collected by and hosted on G2.com.

What do you dislike about Underscore.Js?

Certain utility methods provided by underscoreJS are now natively available in latest versions of Javascript (ES6) and some of the newer libraries like Lo-Dash provide better performance over UnderscoreJS. Furthermore, underscoreJs doesn't support custom per-method packages which means the entire library is downloaded regardless of the methods are actually used - this may lead to a performance bottleneck for the application. Underscore as a library lacks lazy-load and evaluation features as supported by other libraries like lazyJS and Lo-Dash. Review collected by and hosted on G2.com.

"Underscore is good, competent but very vast to learn"
3.5/5
What do you like best about Underscore.Js?

To start with - a lot of functions to help the developers build better applications

- if your website has a lot of data to handle and a lot of client side processing and computations, you probably want to use a library that will help you do those computations and handle the data very easily and conveniently

- There is a vast inner world in underscore, to categorize, there are collections, arrays, functions, objects, utility and chaining

- each of the categories has a wide range of functions, not limited to: search, sort, find at index, math functions, etc.

- if you can code one of the languages such as Java or C with proficiency, you will get along with underscore pretty nicely Review collected by and hosted on G2.com.

What do you dislike about Underscore.Js?

- It's like learning a whole new language

- Other alternatives such as lo-dash offer more functionality and are proven to work faster on some browsers

- page load is very high because of all these computations and the size of the file which is a bit difficult to reduce on mobile phones and the majority of the users are mobile based now Review collected by and hosted on G2.com.

"Underscore.js - The Superhero Utility Belt for Javascript"
4.5/5
What do you like best about Underscore.Js?

underscore.js is an excellent javascript library for working with objects and arrays. The library has many methods that make working with this type of data a breeze. They also offer an annotated source so you can dive into the source and learn how the "magic" methods are performed. Review collected by and hosted on G2.com.

What do you dislike about Underscore.Js?

When using a library, the one that I dislike is that it makes things so easy sometimes that you tend to use the library instead of getting a better understanding of the native way of programming the same functions. Review collected by and hosted on G2.com.
