How do I implement switch statements in JavaScript?

Can you explain how to use switch statements in JavaScript?

Sure! A switch statement evaluates an expression and executes code based on matching cases. Here's a basic structure:

switch(expression) {
  case value1:
    // code to be executed if expression === value1
    break;
  case value2:
    // code to be executed if expression === value2
    break;
  default:
    // code to be executed if expression doesn't match any case
}

What are some common use cases for switch statements?

Switch statements are great for handling multiple conditions based on a single variable, like menu selections or user roles.

Can I use switch statements with strings?

Yes, switch statements can evaluate strings as well! Just ensure your cases match the string values.

Are there any performance considerations with switch statements?

In most cases, switch statements are efficient, but for a large number of cases, consider using an object map for better performance.
