Today, web development is developing rapidly, and the usability and appearance of resources are provided thanks to the work of programmers precisely.
Who Is a Javascript Developer, and What Does He Do
Sometimes a specialist is identified as a frontend developer, but this is not entirely true. He can master both frontend and backend development because, in information technology, JavaScript is the primary skill that everyone who plans to develop must master. In addition, the capabilities of this programming language allow you to make the site more dynamic and exciting to the user.
Intelligent employees are needed today in almost all branches of business. Various websites are regularly created, offering their visitors a variety of goods and services. Even small companies and private entrepreneurs engaged in manufacturing handmade piece goods want to have their trading platform. The competition is significant, so a person who can make a more attractive resource than competitors is valued very highly and can count on temporary employment and a good salary.
The JavaScript developer is mainly engaged in the creation of web pages. Their main task is to write scripts that control interactive elements. If a user visits a website page and sees pop-ups, sliders, and various forms, this is the work of a JavaScript development specialist. In addition to creating websites, the knowledge and skills of a specialist can be used to create:
- browser-based operating systems;
- application software;
- applications for various gadgets, such as smartwatches and smart TVs;
- macros in office applications.
4 Main Advantages of Javascript
It is difficult to find a programming language that would be more in demand today. And in the future, its popularity will not decrease. New goods and services are entering the market, and new businesses and stores are opening. They all need representation on the Internet. So why was this programming language chosen as a development tool? What are its advantages, and what does a javascript programmer do using the functionality of this development tool? We will talk about all this. Let’s first define the main advantages of the JavaScript programming language:
- supported by all modern web browsers;
- the broad scope of application;
- includes a wide range of tools;
- easy to use.
Thanks to such advantages, even schoolchildren can work with it. Today, it is widespread to find training courses for children who are interested in programming. Perhaps in the future, we will get a new generation of people who can independently create websites from scratch even without higher special education.
How the Javascript Programming Language Appeared
The founder of Netscape Communications, Marc Andreessen, decided that web pages should be more dynamic and exciting for the user. One of the ways to make them like this is to fill them with animations that visitors to the resources will interact with
At that time, Java was actively developing, but it was too complicated as a programming language for designers. To create such “chips,” it was necessary to develop a development tool that was as simple as possible and could be used by designers, not just professional engineering developers. So there was an idea to create a new scripting language – Mocha. The parent of the new programming language was Brendan Ike; a little later, due to structural changes in Netscape.
Communications, the company’s marketers, decided to rename Mocha to JavaScript. At that time, he did not have such opportunities as now. The language’s tools were much more modest, used for the most detailed animations and drop-down menus.
Over time, new needs and opportunities appeared, JS developed, and today we have a tool with which even entire software products are created, not just the scripts. At the same time, the requirements regarding
What Personal Qualities Should a Specialist Have
Although the language is relatively easy to learn, a professional developer must have several personal qualities for serious work. Just as not everyone can be a doctor, teacher, marketer, or football player, not everyone who knows the basics of JavaScript can work as a programmer.
All people are different; this profession may seem too monotonous and boring to some. The qualities without which it will be difficult for a person to love his job and enjoy work include:
- assiduity;
- patience;
- pedantry, striving for perfection;
- attentiveness;
- ability to concentrate on details;
- willingness to do detailed work;
- ability to analyze and think logically.
Employers’ requirements for junior and middle specialists in the field of JavaScript development
If you go to any job search site, you can see many vacancies for specialists in JavaScript development. Moreover, many employers are ready to hire candidates without significant experience or even a student. According to the gradation accepted in the information technology environment, such specialists are called junior, from the English word “junior.”
An employee with about two years of work experience can already be considered a middle specialist. Depending on the tasks assigned to the company, the vacancy indicates what a javascript programmer should know and candidates with what work experience will be preferred.
What Employers Expect From Junior
To get a job as a junior JavaScript developer, you need:
- complete the test task;
- master the basics of web development;
- know JavaScript, CSS, TypeScript, HTML, ReactJS, AJAX, GIT;
- take responsibility for your work;
- be able to work in a team.
The listed knowledge and skills may be enough to get your first job. However, whether a candidate will be accepted depends mainly on himself, his resume, and the interview process. The blogs of the LCWork resource have articles with practical tips on how best to design your first resume, what to write if you don’t have work experience yet, and how to prepare for the first interview in the life of an applicant.
What Employers Expect From Middle
Salaries of specialists of this level are higher than those of inexperienced colleagues. But employers also have much higher requirements for them. The primary responsibilities of a javascript programmer in the middle class include:
- development of software products for the employer company;
- modification of the existing program code to meet the requirements of the project;
- program code operability support;
- participation in the code testing process, error correction;
- maintaining code fault tolerance;
- productive interaction of a specialist with web designers, testers, and other developers;
- performing analysis of existing code, detecting and correcting errors.
As we can see, the responsibilities of a javascript programmer are broader than just writing code. To effectively perform the tasks assigned to him, the employee must:
- have practical experience in developing software products and web pages for at least two years;
- understand the work of frameworks and profilers;
- know and be able to work with Windows and Linux operating systems;
- be proficient in JavaScript, HTML, and CSS programming languages;
- be able to work with databases and queries;
- know SQL server;
- be able to work with collective development tools;
- own jQuery, Angular;
- English;
- write code so that it is understandable to other developers;
- interact with testers, and create scripts for automatic testing.
The main task of a javascript programmer is to create a product that will be understandable and comfortable to use for the end user. In the work process, he needs to interact with different team members, so many employers necessarily indicate the ability to work in a team as one of the requirements.
Another point that we focus on is the knowledge of the English language. The modern labor market provides people who know foreign languages with much more opportunities than their colleagues who do not speak at least English. To perform work duties, it may be enough technical, but to communicate with a foreign customer, you need a level of knowledge of English above average.
