React method to implement the multiplication table: 1. Loop tr, and then define a method outside to loop td; 2. Pass each item of tr in the form of parameters; 3. Loop td outside , and then return; 4. The subscripts start from 0, and add 1 one by one to multiply each row.

How to implement the multiplication table in react?
React implements the multiplication table
- The first step loop tr and then define a method outside to loop td
- In tr, we need to write td. We pass each item of tr in the form of parameters.
- Loop td outside and then return it. We need to calculate so We also need to pass the following table
We also need to multiply, so we need to multiply with each row. The subscript starts from 0, so we need to add 1
- The above is how to implement a simple nine-nine multiplication table
- The following code mainly implements the interlaced color changing function and crosses the select option box with special effects
The main implementation idea is to loop the two-dimensional data map multiple times and use setState in react to modify the data.

React's componentized architecture makes scalable UI development efficient through modularity, reusability and maintainability. 1) Modularity allows the UI to be broken down into components that can be independently developed and tested; 2) Component reusability saves time and maintains consistency in different projects; 3) Maintainability makes problem positioning and updating easier, but components need to be avoided overcomplexity and deep nesting.

React's one-way data binding ensures that data flows from the parent component to the child component. 1) The data flows to a single, and the changes in the state of the parent component can be passed to the child component, but the child component cannot directly affect the state of the parent component. 2) This method improves the predictability of data flows and simplifies debugging and testing. 3) By using controlled components and context, user interaction and inter-component communication can be handled while maintaining a one-way data stream.
