Being located in Ukraine and having 5+ years of experience in staff augmentation, Orange Sputnik creates the most suitable conditions to hire developers for startups and IT businesses from abroad.
There is no definite and undeniable answer on this question as many variables exist. The list of the most important aspects that may influence the choice looks like the following:
Traditionally, different startuppers have diverse conditions and opportunities, which led to the appearance of all the approaches. Thus, Native is the most reliable method, but also the most time- and cost-consuming one. Cross-platform and hybrid are cheaper and faster while they are restricting functionality, speed, and UI/UX features. Furthermore, the decision between the last ones can be made even on the already presence of the specific developer in the team who can fastly adjust the app code to the market needs.
One of the most popular environments to write a server-side is Node.js. This trendy approach is usually used for mid-size applications and suggests asynchronous platform for implementing creative solutions. It also has reliable performance/efforts ratio, which is only facilitated with the general JS idea of making dynamic web pages on both sides of the applications.
One more variant to rely on while working with JS back-end solutions is Express.js, which is called a ‘standard server framework’ for Node.js. This product is quite smaller and has less functionality compared to Meteor.js, but possibilities can be added via specific plugins. In other words, it is an underlying platform for creating applications with RESTful APIs.
Although, every conversation inside this topic should contain information about frameworks and libraries as those instruments are an inevitable part of a professional JS programmer. A framework or a library is, actually, a set of decisions and approaches in the form of already done pieces of code. As multiple functions repeat throughout programs and applications, programmers use those ready pieces instead of writing code from scratch.
There are no doubts that React is the most popular JS framework currently, but the number of programmers that want to try VueJS makes it the most fast-growing and perspective approach. The top-3 closes Angular (AngularJS and Angular 2+ simultaneously), which also holds a great piece of JS frameworks’ pie.
Although one has to understand that those approaches are recently developing and will get regular updates in future, so the situation can change any time. Therefore, if you are looking for the best framework for building a new web application, you should evaluate pros and cons of the top propositions in terms of technological methods that are essential in the particular case. Another crucial element for young entrepreneurs is to understand the correlation between the popularity of framework and number of available software developers (and ease of their hiring, as a result).
The situation with defining the best JS libraries is quite different compared to frameworks, and here Skillcrush detection mechanism comes to the rescue. According to this approach, about 30% of websites are using a few JS libraries simultaneously. It leads to about 1,3 million JS library detections in 1 million most popular worldwide websites. The spread chart is presented below:
The dominance of jQuery is astonishing due to its open-source status and variety of the tasks it can solve and simplify. The other JS libraries are not so often used but help in resolving specific tasks. Also, one should understand that Mentioned libraries have some pitfalls in understanding them.
We advise providing an in-depth analysis of the workplace aspects and job duties before sending a request, and the list of elements to think about and understand looks like the following:
As a rule, the most expensive programmers are located in the NA and Western Europe, while the most attractive prices for startups can be found in Eastern Europe. Moreover, this region has a massive talent pool of developers with appropriate knowledge of English, while the time gap absence, especially for Europeans, is also a benefit.
Without a doubt, it is not a full list of technologies that are related to JS, but it is a core to form questions for the interview. Moreover, none of the existing programmers knows all the technologies mentioned above, so you should ask only about the needed ones. It would be better to dig deeper inside one specific technology and ask about APIs realisation via back-end framework or the DOM structure realisation in React, for instance.
All in all, the recruiting process is not the simplest task, so if some other question arose in your mind - feel free to ask our managers.
In order not to overload a reader with tons of wages’ statistics, we prepared a short overview of the most important numbers. We decided to focus on the global wages’ overview for JS developers, determine the dependence of wages towards experience, and to look inside the language to define trends across most popular frameworks.
We took data of PayScale to define not only the absolute difference among salaries but also to determine the growth percentage depending on the years of experience. The resulting chart is presented below:
The essential aspect this diagram highlights is the stable growth of salaries with receiving experience. Even though data are based on the US wages only, we defined that the average growth rate between the stages is about 1,1, which means that the salary will grow approximately by 10% with every experience stage. We can assume that such a growth rate is actual to other countries, so one can easily calculate future income.
Another important element relates to locations. Thus, the US and Switzerland are well-known destinations to earn more than in other countries, which is directly related to the level of life in those countries. The similar situation is with the Scandinavian region, where the level of life is facilitated with the high taxes rates. On the contrary, East Europe and Ukraine, in particular, look more friendly towards potential remote employers in JS programming.
The final section will be dedicated to the top-3 most popular JS frameworks used at the front-end of web development. According to Glassdoor.com, the distribution looks like on the following chart:
According to the comparison table of JS frameworks salaries from mentioned countries, we may assume that most well-paid specialists are those who know Vue.js with the average salary of almost $66k annually. The second place takes React with slightly more than $61k per year, while Angular is not far away with almost $60k annual wage. However, those numbers are average for only 9 countries, while the distribution of JS frameworks popularity varies significantly. Nevertheless, Vue.js should be admitted as it showed both the best growing trends and the best average salary.
