#10 JavaScript Tutorial | Switch case 2019
You can use multiple if…else…if statements to perform a multiway branch. However, this is not always the best solution, especially when all of the branches depend on the value of a single variable. Starting with JavaScript 1.2, you can use a switch statement which handles exactly this situation, and it does so more efficiently than repeated if…else if statements.
The switch case statement in JavaScript is also used for decision making purposes. In some cases, using the switch case statement is seen to be more convenient over if-else statements. Consider a situation when we want to test a variable for hundred different values and based on the test we want to execute some task. Using if-else statement for this purpose will be less efficient over switch case statements and also it will make the code look messy.
