What is jQuery?
All a web developer had to do was install jQuery and use prewritten code snippets to manipulate the virtual DOM. For example, if a developer wants to add an autocomplete feature in a search bar on their site, they would insert the appropriate jQuery code snippet into the project’s code. When a user enters text into the search bar, the jQuery code snippet retrieves the feature from the jQuery library and displays it in the user’s modern browser.
What is React JS?
The web component-based library allows developers to avoid the pitfalls of rewriting code and dealing with complicated debugging. With React, you can reuse and recycle different components across the web application or other products.
Components such as navigation bars, buttons, cards, forms, sections, and the like can all be reused like little building blocks that make the web application. A library like React dramatically increases the development speed with fewer bugs and makes extremely performant applications.
Library vs. Framework
Perhaps one of the most common topics of discussion in the software community is the difference between a library and a framework. As we see above, jQuery and React are libraries with prewritten code snippets that we can use and reuse to build applications.
The advantage of frameworks is the overall efficiency and organization. The disadvantage is that a developer has less freedom to work around the rules and conventions specific to a particular JS framework. Libraries, on the other hand, give developers more freedom to use different code and snippets but do not provide the type of structure and convention that comes with a framework.
