JavaScript allows you to change page styles, images, perform actions with tags and make changes to the codes. The scope of application of this language is not limited by anything. The popularity of Javascript programming language is due to the following:
- It has no analogues. This means that web development cannot do without this programming language. High speed of work. JavaScript does not affect the server running in the user’s browser.
- Ample opportunities for the programmer. With JavaScript, you can specify a specific set of commands that perform a wide range of capabilities.
- High level of user interfaces. You can configure absolutely everything: filling out forms, activating buttons, responding to the slightest mouse movement.
Despite its ubiquitous use and prevalence, JavaScript has a number of drawbacks. Among them:
- Security level. All source codes are freely available, there is no guarantee that an application running on JavaScript cannot be hacked.
- Widespread. If in the near future there is a more convenient language that solves the same tasks, but faster, all applications using JavaScript will stop working.
- Do not work remotely. Cannot be used for programs and applications that run on the same network and must be managed from a single server.
Everyone makes their own choice whether to use JavaScript or not. To make the right decision, you need to understand for what tasks it is needed. It should be remembered that this language is simple and accessible, this is enough to use it. On the resource doclets.io you can see examples of beautiful Javascript API documents.
