I"ve never thought about render performance before writing vue, and I"ve never heard of the need to write performance-optimized code.
recently writing react, found that it is necessary to use PureComponent, shouldComponentUpdate and other means to write performance-optimized code.
is it true that the performance of react is not as good as that of vue? without optimizations such as shouldComponentUpdate?
performance optimization is not determined by shouldComponentUpdate, etc. No one is inferior to others
