Switch-Case in JavaScript
Switch-case statements in JavaScript provide a way to execute different blocks of code based on the value of an expression. This control flow structure is useful when you have multiple conditions to check against a single variable. Instead of writing a series of if-else statements, switch-case statements offer a more concise and readable solution.
In this article, we'll explore the syntax, usage, and best practices for switch-case statements in JavaScript.
The basic syntax for a switch-case statement is as follows:
switch (expression)
{
case value1:
// code to execute if expression matches value1
break;
case value2:
// code to execute if expression matches value2
break;
// more cases...
default:
// code to execute if expression doesn't match any case
}
