Question 8

Why React?

Answer 8

• With vanilla JavaScript, the UI state becomes difficult to manage. In larger JS applications, you have manually target elements in your DOM and if you change the structure of your HTML code, chances are you will need to change the way you targeted your elements because you used query Selector.
• Even if you use jQuery, traversing the DOM is easier, but it’s still always something you have to keep in mind.
• React helps us by making the whole UI state management a non-issue, allowing you to dynamically add and remove ingredients.
• Allows us to focus on business logic, not preventing your app from exploding.
• Has a huge ecosystem, active community, high performance.
