Underscore.Js Reviews & Product Details

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.

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.

It is one of the most widely-know open source projects the Javascript programming world. The best functionality it feats 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 otherway they would need to code, test and maintain themselves. Review collected by and hosted on G2.com.

In case you want to use Underscore in your project, you would need to include th whole library inside your project. That could impact performance when serving a web to your customer, in the sense 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Also, in some parts of the library, it seems to be a bit outdated.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 taking a look at the documentation. It is very complete, but a bit chaotic when defining some functions. Review collected by and hosted on G2.com.

I like the modular form of the framework and the multiple functions for resolve the commons problems when programming arrays, collections and objects of javascript language. Review collected by and hosted on G2.com.

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

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.

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.

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.

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.

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.

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.

The library has as a load of reusable cross-browser functions that perform common operations but with better performance gains Review collected by and hosted on G2.com.

As a free helper library, I don't think I'd dislike anything about it. Review collected by and hosted on G2.com.

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.

- 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 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.

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.

I love how easy it is to map arrays to destination objects, and also there are nice filter and find functions available. Review collected by and hosted on G2.com.

I honestly don't like using an underscore right before placing a period, I think it looks weird in the code. Review collected by and hosted on G2.com.
