How does the performance of a switch-case statement compare to if-else if-else chains, especially when dealing with a large number of conditions? 

  • switch-case is always slower than if-else chains. 
  • switch-case and if-else chains have similar performance. 
  • if-else chains are always slower than switch-case. 
  • Performance is dependent on the compiler optimization.
While the performance of switch-case statements and if-else chains can depend on various factors, often, the switch-case statement is more optimized by compilers when dealing with a large number of conditions. The reason being, the compiler can optimize switch-case into a jump table or an array of branch instructions. However, it's always crucial to profile code in practice as the optimization might vary with compiler implementations and versions.
