Its name, “ memo ” comes from memoization, which is basically a form of optimization used mainly to speed up code by storing the results of expensive function calls and returning the stored result whenever the same expensive function is called again. According to the documentation , this exists only as a performance optimization.

If you're a beginner, a more robust framework like Bootstrap may be in order, as it comes prepackaged with many useful widgets and requires minimal coding skills. Pros: React's reusable components ensure that developers don't have to rewrite the same code over and over again. This framework's main claim to fame is its simplicity.

Like React, Vue features two-way binding, uses components and a virtual DOM. This JS library uses elements – isolated items of code that may be used to create a lot of complicated logic and UIs. They use lazy loading to extend performance rates and reduce loading times and code refreshes via virtual DOMs. What is React?
