4 Reasons to Avoid Using Array.reduce

With the functional programming (FP) paradigm rising, the way we build JavaScript applications changes each year. Array methods are quite popular for this reason because you can chain them (e.g. map.filter.map.flatMap). Some developers treat using the standard for or while loops as old-school.

One of the methods is Array.reduce. It is not as straightforward as other standard Array methods, for example:Array.filter or Array.map. In this article, I want to talk about Array.reduce’s potential downsides and show you that you may not need to use it. Let’s start.

1. Array.reduce Can Be Hard to Understand

If you search for Array.reduce on Medium, most articles focus on explaining how it works. When I google “Array.reduce explain” (without quotes) in a private window, I get 190M results, but when I do the same search as “Array.filter explain”, I get 93M results. That is a sign that Array.reduce is not as straightforward as the other Array methods.

The reasoning behind the “accumulator” variable is not trivial at first look. If you don’t understand Array.reduce, I suggest reading one of the articles before continuing. I’ll wait.

You may already feel comfortable working with Array.reduce if you come from a functional programming (FP) background. But although JavaScript provides necessary built-ins to support FP, most JavaScript developers aren’t (yet) familiar with it. I have worked with many talented JavaScript developers who struggled with Array.reduce.

Therefore, consider writing the same logic differently before using Array.reduce . Although a different version won’t guarantee more readability, it gives you a chance to compare. It might help future readers to understand it easily.

Why Use WordPress? What Can You Do With WordPress?

Can you use WordPress for anything other than blogging? To your surprise, yes. WordPress is more than just a blogging tool, and it has helped thousands of websites and web applications to thrive. The use of WordPress powers around 40% of online projects, and today in our blog, we would visit some amazing uses of WordPress other than blogging.
What Is The Use Of WordPress?

WordPress is the most popular website platform in the world. It is the first choice of businesses that want to set a feature-rich and dynamic Content Management System. So, if you ask what WordPress is used for, the answer is – everything. It is a super-flexible, feature-rich and secure platform that offers everything to build unique websites and applications. Let’s start knowing them:

1. Multiple Websites Under A Single Installation
WordPress Multisite allows you to develop multiple sites from a single WordPress installation. You can download WordPress and start building websites you want to launch under a single server. Literally speaking, you can handle hundreds of sites from one single dashboard, which now needs applause.
It is a highly efficient platform that allows you to easily run several websites under the same login credentials. One of the best things about WordPress is the themes it has to offer. You can simply download them and plugin for various sites and save space on sites without losing their speed.

2. WordPress Social Network
WordPress can be used for high-end projects such as Social Media Network. If you don’t have the money and patience to hire a coder and invest months in building a feature-rich social media site, go for WordPress. It is one of the most amazing uses of WordPress. Its stunning CMS is unbeatable. And you can build sites as good as Facebook or Reddit etc. It can just make the process a lot easier.
To set up a social media network, you would have to download a WordPress Plugin called BuddyPress. It would allow you to connect a community page with ease and would provide all the necessary features of a community or social media. It has direct messaging, activity stream, user groups, extended profiles, and so much more. You just have to download and configure it.
If BuddyPress doesn’t meet all your needs, don’t give up on your dreams. You can try out WP Symposium or PeepSo. There are also several themes you can use to build a social network.

3. Create A Forum For Your Brand’s Community
Communities are very important for your business. They help you stay in constant connection with your users and consumers. And allow you to turn them into a loyal customer base. Meanwhile, there are many good technologies that can be used for building a community page – the good old WordPress is still the best.
It is the best community development technology. If you want to build your online community, you need to consider all the amazing features you get with WordPress. Plugins such as BB Press is an open-source, template-driven PHP/ MySQL forum software. It is very simple and doesn’t hamper the experience of the website.
Other tools such as wpFoRo and Asgaros Forum are equally good for creating a community blog. They are lightweight tools that are easy to manage and integrate with your WordPress site easily. However, there is only one tiny problem; you need to have some technical knowledge to build a WordPress Community blog page.

4. Shortcodes
Since we gave you a problem in the previous section, we would also give you a perfect solution for it. You might not know to code, but you have shortcodes. Shortcodes help you execute functions without having to code. It is an easy way to build an amazing website, add new features, customize plugins easily. They are short lines of code, and rather than memorizing multiple lines; you can have zero technical knowledge and start building a feature-rich website or application.
There are also plugins like Shortcoder, Shortcodes Ultimate, and the Basics available on WordPress that can be used, and you would not even have to remember the shortcodes.

5. Build Online Stores
If you still think about why to use WordPress, use it to build an online store. You can start selling your goods online and start selling. It is an affordable technology that helps you build a feature-rich eCommerce store with WordPress.
WooCommerce is an extension of WordPress and is one of the most used eCommerce solutions. WooCommerce holds a 28% share of the global market and is one of the best ways to set up an online store. It allows you to build user-friendly and professional online stores and has thousands of free and paid extensions. Moreover as an open-source platform, and you don’t have to pay for the license.
Apart from WooCommerce, there are Easy Digital Downloads, iThemes Exchange, Shopify eCommerce plugin, and so much more available.

6. Security Features
WordPress takes security very seriously. It offers tons of external solutions that help you in safeguarding your WordPress site. While there is no way to ensure 100% security, it provides regular updates with security patches and provides several plugins to help with backups, two-factor authorization, and more.
By choosing hosting providers like WP Engine, you can improve the security of the website. It helps in threat detection, manage patching and updates, and internal security audits for the customers, and so much more.

Java Stream Reduce

Java Stream Reduction is a terminal operation that aggregates a Java Stream then returns one value by combining the contents of a stream.

Many reduction operations perform a specific task such as: average, sum, min, max, and count.

  • Examples:
  • Initial Java List:
List<Integer> intLst = Arrays.asList(1, 3, 5, 2, 9, 8, 15, 12);
  • How to sum all Element of a Stream?
int totalOpt = intLst.stream().mapToInt(i->i).sum();
System.out.println(totalOpt);
// 55
  • How to get average value of an Integer List?

OptionalDouble averageOpt = intLst.stream().mapToInt(i->i).average();
averageOpt.ifPresent(System.out::println);
// 6.875
  • How to get Min/Max value of an Integer List?

/* Get Min Value */
OptionalInt minOpt = intLst.stream().mapToInt(i->i).min();
minOpt.ifPresent(System.out::println);
// 1

/* Get Max value */
OptionalInt maxOpt = intLst.stream().mapToInt(i->i).max();
maxOpt.ifPresent(System.out::println);

JavaScript Array Methods #9: Array .reduce() Method

The JavaScript Array reduce() method executes a reducer function on each element of the array and returns a single output value. Reduce comes with some terminology such as reducer & accumulator. The accumulator is the value that we end with and the reducer is what action we will perform in order to get to one value.

Syntax:
array.reduce(callback(currentvalue, index, arr), thisArg)
