LODASH a big library and to be precise a utility library delivering consistency, customization, performance, & extras. Lodash was built with modularity and performance in mind from ground up. Lodash offers more flexibility allowing custom builds targeting different environments including ES2015 modules, excellent libraries that have huge adoption and years of development by the best and brightest of the JavaScript community. Lodash and underscore come with immutable operations of their own. Each comes with an API of its own. Lodash has so many qualities by which it has replaced underscore::

Usability Improvements
Extra Functionality
Performance Gains
Shorthand syntaxes for chaining
Custom Builds to only use what you need
Semantic versioning and 100% code coverage

One will get immutability and more power but there’s simply more to learn. Lodash also contains a group of functions that target functional programming. Lodash has a group of general purpose utilities for simplifying common programming tasks. Lodash seems to be a drop-in replacement for underscore. It has since become a superset of Underscore, providing more consistent API behavior, more features, more thorough documentation and unit tests better overall performance and optimizations for large arrays/object iteration, and more flexibility with custom builds and template pre-compilation utilities.

Elasticsearch

Elasticsearch is a distributed open source, full text search and analytics engine. It is powered by Lucene, a powerful open-source full-text search library. Elasticsearch is an open-source, broadly-distributable, readily-scalable, enterprise-grade search engine. Accessible through an extensive and elaborate API, ELASTICSEARCH can power extremely fast searches that support your data discovery applications. It provides fast data retrieving because it allows cluster and node thing and the way of storage by distributing data in index , then it’s worked on shards n replicas that makes it faster to search. The core features that are required to build applications for powerful searches are found in Elasticsearch that range from the intranet to the searches of e-commerce websites. For e-commerce related websites, it gives the option for enabling a high level of reliability, flexibility, relevance, etc. and some particular features that help in conversion and retention.

– Elasticsearch is primarily used when there is a lot of text. Traditional RDBMS don’t perform well for text search. Elasticsearch is highly customizable, extendable through plugins. One can build robust search without much knowledge quite fast.

– Along with Logstash, it is used to store and centralize logs from various sources. Integrating Kibana lets one connect to Elasticsearch cluster and create visualizations straight away. GrayLog is also using ElasticSearch as backend to store logs.

– The ELK stack can interactively search, discover, and analyze to gain insights that improve your products. It is used in the analysis of time-series data such as social media.

– Combining above uses, Elasticsearch enables enterprise search which includes Document Search, E-commerce product search, blog search, people search, site search in all its forms.

A huge amount of data affects the usability of the system performance and query response time. Using Elastic search query response time can significantly reduced.

Scala

SCALA is a general purpose programming language. Scala is fashionable because it helps people solve real problems in an elegant way and runs on what is arguably one of the better platforms (the JVM) currently available and pervasively deployed. Combining object oriented programming and functional programming into one, Scala is exceptionally expressive and concise. Scala is on the JVM, thus accessible to the most resourceful ecosystem amongst all languages. If you want your code to be something other programmers can use and/or build on, Scala is your best choice at the moment — it creates .jar files which can be used directly from plain Java, whereas Go doesn’t seem to be capable of creating reusable shared object (.so) files.

Simple and straightforward syntax– Scala typically requires two-thirds less code than Java. The syntax is also more flexible. For example, you can leave out periods between method calls so the code is more human-readable and easier to understand.
Inherently immutable objects– Scala’s programming language reduces many thread-safety concerns that spring up in traditional Java applications.
Highly functional. Scala treats functions as first class citizens.
Fast implementation speed– It allows for quicker implementation and enhanced performance.
Scala challenges strong engineers in a meaningful and entertaining manner, making development more fun.
Easy to solve concurrency issues– It has an Actor library to solve concurrency problems more rapidly.
Support XML — Scala supports XML, which is beneficial if you have a need to encode documents in your products.

REST APIs

REST is an architectural style that uses simple HTTP calls for inter-machine communication instead of more complex options like CORBA, RPC, or even SOAP. Using REST means your calls will be message-based and reliant on the HTTP standard to describe these messages. Using the HTTP protocol means REST is a simple request/response mechanism. Each request returns a subsequent response.
It works because you’re not tying your API to your client-side technology. One could imagine that this API is accessible from a client-side Web project, an iOS app, an IoT device and even a Windows Phone.
Rest states “representational state transfer”, is an architectural style consisting of a coordinated set of components, connectors, and data elements within a distributed hypermedia system, where the focus is on component roles and a specific set of interactions between data elements rather than implementation details. REST API is providing various URIs to client side technology (Front end technology) from where client side technology fetches the data. REST APIs is the internet (web) way on how you do ‘stuff’ on your ‘things’ providing/obtaining the required ’information’ in the process. In other words, it is the web language that allows you to perform operations on resources providing details in the ‘request’ and getting back details in the response.

An API (Application Programming Interface) is best thought of as a contract provided by one piece of computer software to another. API is a set of routine definitions, protocols, and tools for building software and applications. A good API makes it easier to develop a program by providing all the building blocks, which are then put together by the programmer. APIs often come in the form of a library that includes specifications or routines, data structures, object classes and variables. An API can also be related to a software framework, a framework can be based on several libraries implementing several APIs, but unlike the normal use of an API, the access to the behavior built into the framework is mediated by extending its content with new classes plugged into the framework itself.

With an API , the exact structure of request and response is documented upfront and is likely to remain constant, regardless of whether the website changes its look and feel for human visitors. Without an API , app relies on the website never changing its look. If it does, app may stop working because it can’t parse the webpage anymore. Computers are only as smart as the software you write. Hence , API production allows you to coordinate more efficiency, automation, integration, personalisation, mashup etc.
