    If your primary focus is learning a programming language that will always be useful, then JavaScript fits the bill. JavaScript is relatively simple to learn, can work smoothly with other languages in a variety of applications, can be run quickly in the client-side browser (Server-side as well using NodeJS), and is found just about everywhere on the internet.

    Web and mobile development, game development, and desktop app development, JavaScript is an indispensable language that continues to improve.

    TypeScript, a superset of JavaScript, was considered one of the most loved languages of 2019. Even Facebook agrees as they moved Jest (JavaScript Testing) from Flow (another programming language) to TypeScript at the beginning of last year.

    Where To Learn It

    There is no better time to learn JS than in 2020 as it is now, as it has been for the last decade, one of the most demanded programming languages on the market.

    Another language that dominates the internet, primarily in the form of dynamic data-heavy websites and app development, is PHP. Some of the bigger contributions of PHP can be found in sites like WordPress and Facebook. 

    PHP has been around for a very long time and is regarded as a must-know programming language. It’s an open-source language and also considered rather slow in terms of web development when compared to its peers.

    It being open-source means that it’s not a very secure programming language but does have a rather large open-source software community to back it up. Learning PHP takes minimal time investment and can aid you in employment opportunities (though dwindling) for web applications, content management systems, and eCommerce applications.

    Where To Learn It

    Web developers interested in PHP will find plenty of knowledge shared in Coursera’s Building Web Applications in PHP course. Have your heart set on creating an e-commerce site? Check out Learn E-Commerce Website in PHP & MySQL From Scratch found on Udemy.

    This programming language was designed specifically for iOS apps. Apple decided back in 2010 that it didn’t want to force iOS developers to work with Objective-C so Swift offers those developers an alternate language to work with. Anyone still using the Cocoa Touch libraries for interactions may still use Objective-C as the frameworks used by both remain unchanged.

    Swift offers real-time output for interactivity and fast response to code or debugging changes on the fly. The automated debugging system is actually one of the key elements of the Swift system providing it more interactive properties that are common with scripting systems similar to Python.

    The advantages Swift has over a language like Objective-C is code reduction (by almost a fourth), it’s far easier to learn, and the developer community has more potential for growth due to the quality of apps it’s more likely to produce. Anyone hoping to get into iOS app development or simply wants to join the workforce using what may just be the most lucrative programming language moving forward would do well to learn Swift.

    Where To Learn It

    Like most of the entries on our list, Udemy is a great source of knowledge on this programming language. Check out there iOS 11 & Swift 4 – The Complete iOS App Development Bootcamp to take the path of beginner to pro.

    Just looking to see what it’s all about? There’s a nifty tutorial courtesy of DZone.com that can walk you through a few things. To understand the fundamentals of iOS 11, this course on pluralsight.com will get you started.

    SQL & NoSQL

    What are the Best Programming Languages to Learn in 2020? image 10

    SQL has been around for a very long time. The purpose of SQL is as an application’s backend database. As a standalone language, SQL may not seem as beneficial. However, as a software developer, regardless of the language you choose, understand both the database and SQL are a necessity.

    When it comes to data queries, availability, and consistency, SQL provides. If there is a need to retrieve data from multiple tables within the database, SQL will deliver that information swiftly. The entire language has been optimized for large numbers of table rows and expedient searches throughout the entire database for what project you’re working on.

    As powerful as SQL is, it does come with considerable drawbacks including difficulty converting data from objects into database tables, single server availability, and everything needs to be written out, unlike ORM which allows for an auto-generated solution. Though to be fair, writing most of SQL by hand tends to lead to a tighter, more high-performance query than that of ORM. Anyone with an interest in the Data Science career field will do well to learn SQL. 

    NoSQL has been gaining popularity due to its performance on low-cost hardware, the elasticity and scalability it offers over other kinds of available databases, and making database model structuring unnecessary. It has the potential to overtake SQL in the data science field but nothing yet points to this as fact. As it is a newer language it lacks community support (though this is rapidly expanding) and a standardized platform.

    When you stack up SQL vs NoSQL, the structured data, integrated support system, and schemas of SQL make it the preferred choice for businesses, whereas NoSQL may find that swift application development to be more its niche.

    Where To Learn It

    For SQL, Code Academy can get you started with one of their courses. NoSQL enthusiasts can find plenty to learn from edx.org’s courses on Introduction to NoSQL Data Solutions and Amazon DynamoDB: Building NoSQL Database-Driven Applications.

    Other Useful Programming Languages To Learn

    Looking over the list, you may or may not notice a few missing that you would have assumed to be present. Mainly that of Ruby and its framework Ruby on Rails (RoR), seeing as it is a language used in many web apps and still in decent demand today. It’s been used in Shopify, Airbnb, Fiverr, Github, and Bloomberg to name a few. Though plenty of companies are still using it, it has lost a lot of its hype over the last few years and as such cannot be recommended as a “must learn”.

    Other lesser-known programming languages like R, Rust, Kotlin, and Golang, haven’t reached the popularity to make them seem worth knowing at this time. However, we think that Kotlin would benefit anyone serious about Android app development as word on the street is that it could be the next big thing.

    Golang, also referred to as Go, is pretty difficult to learn but anyone interested in developing frameworks may find it worth their time. Along the same line as Go, you’ll find that Rust, also a really difficult language to learn, can be very rewarding.

    It has the ability to create libraries that are capable of linking to other programming languages. If interested, Rust for Undergrads should help get the ball rolling.
