In our post about the “Best Programming languages for 2017” over 10,000 readers voted for their favorite language. Here are the results. (Don’t worry: You get to vote this year, too. Just scroll to the end of the post)<\/b><\/p>\n\n\n\n\n\n\n <\/p>\n\n\n <\/p>\n\n\n\n JavaScript was by far the winner of our poll.<\/p>\n\n\n\n After doing some research on sites like TIOBE, Trendy Skills, PYPL, Indeed, Google Trends, and after speaking with many leaders in the industry, the most popular programming languages in 2018 are – in no particular order:<\/p>\n\n\n\n When looking at different sites, the ranking of the most popular languages can vary, depending on the parameters you use for your calculation.<\/b><\/p>\n\n\n\n For example, according to the TIOBE’s Community Index<\/a>, Java is the most popular language in 2018, followed by C and then C++. (The TIOBE Index is calculated by using the results of 25 search engines and their most frequent searches. Apart from Google and Yahoo, they also include eBay, YouTube, and Baidu among others.)<\/p>\n\n\n <\/p>\n\n\n\n If you look at PYPL<\/a>, the ranking is different:<\/p>\n\n\n <\/p>\n\n\n\n While Java is still #1, it is followed by Python and PHP. The PYPL ranking is created by analyzing how often language tutorials are searched on Google.<\/p>\n\n\n\n As you can see: a different approach leads to different results.<\/p>\n\n\n\n One last example, to illustrate my point.<\/p>\n\n\n\n Here are the most popular programming languages used at Github<\/a>:<\/p>\n\n\n <\/p>\n\n\n\n Javascript is #1 here, followed by Python and Java.<\/p>\n\n\n\n Ranking depends on what you are asking and who you are asking. That is something that you should keep in mind<\/b> when using trend data to determine which programming language to learn next.<\/b><\/p>\n\n\n\n We don’t want to give you yet another ranking, but instead, show you 10 widely used programming languages and how people are using them.<\/p>\n\n\n\n Have fun and don’t forget to vote for your favorite programming language at the end of the post.<\/p>\n\n\n <\/p>\n\n\n\n JavaScript<\/b><\/a> is one of the most commonly used programming language in the world<\/b>.<\/p>\n\n\n\n Javascript improvements such as ES6 and ES7 have launched recently and made developers weep out of joy. Examples are:<\/p>\n\n\n\n Arrow functions reduce boilerplate when writing functions. Let\u2019s take a look at one specific example:<\/p>\n\n\n\n We can simplify this example with arrow functions:<\/p>\n\n\n\n Object spread makes it really easy to avoid mutating objects because it is so much easier to create new objects that contain existing values. Here\u2019s an example demonstrating it:<\/p>\n\n\n\n Sometimes we do need to call functions that have side effects, even in functional programming \u2013 e.g. when we\u2019re talking to our backend. Often we even have multiple calls that depend on each other. First, there was callback hell, then came promises, and now async\/await has come to make these things even easier.<\/p>\n\n\n\n An excellent guide for learning or deepening your knowledge in JavaScript is the book “Professional JavaScript for Web Developers<\/a>” by Nicholas Zakas. It is the ultimate collection of tutorials explaining language basics, variables, scope, references types and function expressions. JavaScript has been described as a language that takes minutes to learn, but years to master. This book is a great resource for everyone, no matter if you are a beginner and are reading it cover to cover, or if you are already an expert an use it occasionally to look up a reference type.<\/p>\n\n\n\n If you want to take a deep dive, Douglas Crockford\u2019s \u201cJavaScript \u2013 The Good Parts<\/i><\/a>\u201d will walk you through all the peculiarities of JavaScript.<\/p>\n\n\n\n To illustrate each programming language even more, we want to show you the bubble sort algorithm for each language. Bubble sort is a sorting algorithm, which compares adjacent items and swaps them if they are not in the right order. Here is what Wikipedia<\/a> has to say about it:<\/p>\n\n\n\n \u201cThe algorithm, which is a comparison sort, is named for the way smaller or larger elements “bubble” to the top of the list.\u201d<\/p>\n<\/blockquote>\n\n\n\n Here is the famous bubble sort algorithm written in JavaScript<\/a>:<\/p>\n\n\n\n Recommend reading: Why we have to talk about client-side JavaScript error logging!<\/a><\/p>\n\n\n <\/p>\n\n\n TypeScript<\/b><\/a> is a statically typed language that compiles to JavaScript. Version 2.1 includes all the new features of JavaScript with optional static types. Other benefits are stronger checks against bugs in your code and typos, async\/await and more<\/a>. According to Google Trends<\/a>, the interest in TypeScript is continuously high. (The dip on the right hand is due to the holidays season)<\/p>\n\n\n\n![\"Programming](\"https:\/\/usersnap.com\/blog\/wp-content\/uploads\/2018\/01\/Programming-Languages-2017_results-1.png\" "\\"Programming")
