Javascript is a unique scripting language used for programming. It has support for functional, event-oriented and oriented style, suitable for the development of various applications, interactive web resources. Javascript is especially popular with programmers, large recruitment agencies and other companies. Often the language is used to create mobile applications, various programs and server development.
The benefits of Javascript include:
- It is considered indispensable for web development;
- It has decent performance and maximum speed, so Javascript helps to process web pages without using a server, which saves time;
- Powerful ecosystem;
- Rationality in use, because you can solve a simple problem in just 5 minutes;
- Convenient user interface, because the user is presented with the activation of various buttons, filling out forms, checking the reaction to mouse clicking and hovering;
- Easy to learn syntax.
The disadvantages of Javascript include:
- There is no function of reading, downloading a file, which is explained by security;
- Not strict typing and a fairly free interpretation. The interpretation of data may be different, there is no possibility of timely detection of errors, which is noticed already during operation;
- There is no support for remote access, so you will not be able to use the language for network applications;
- Accessibility for scammers, because you can insert a code fragment with a virus into the scripting language, so the user will have to rely only on an antivirus program.
Javascript developers are constantly improving the language and functionality, eliminating all existing shortcomings. Thanks to the release of HTML5, unique features of the scripting language appeared. You can see examples of Javascript API documents on the https://doclets.io/ website.
Is it promising to study Javascript as a programmer now?
Javascript is the most popular language used in programming. It provides interactive support for sites and is especially popular in popular browsers. Now the popularity of mobile applications is actively growing, so the scripting language is actively promoted in Google. Progressive applications are a hybrid of a mobile program and a website, and it is important to use Javascript to develop them. This indicates that the scripting language is in demand and will be popular in the near future. It is the only high-level dynamic language that cannot be replaced by other programs.

- The first stage is that the beginner studies for 3 months. At this stage, the programmer gets acquainted with the syntax of the language, learns the basic concepts of variables. The main goal of the initial stage is to get acquainted with Javascript and understand the programming language in order to learn how to write code;
- The second stage is an advanced beginner, which lasts from 4 to 6 months. By this time, the student should have mastered the basic concepts and mechanisms;
- The third stage is the average level, which lasts from 7 to 9 months. The programmer already knows all the concepts of Javascript and can work on deepening. For two months, the student spends time writing code and goes through practical tasks;
