When should I use switch case in JavaScript?

As it turns out, the switch statement is faster in most cases when compared to if-else , but significantly faster only when the number of conditions is large. The primary difference in performance between the two is that the incremental cost of an additional condition is larger for if-else than it is for switch .

The switch statement evaluates an expression, matching the expression’s value to a case clause, and executes statements associated with that case , as well as statements in case s that follow the matching case .2 gün önce
