It's used to test a condition only if the preceding if condition is false
The else if statement in JavaScript is used to test a condition only if the preceding if condition is false. This creates a chain of conditional tests where each subsequent else if is only evaluated if all previous conditions were false. For example: if(condition1) { ... } else if(condition2) { ... } else { ... }. If condition1 is true, condition2 is never evaluated. This structure provides a clear and efficient way to test multiple conditions in sequence, executing only the code block associated with the first true condition (or the else block if all conditions are false).
It's used to execute code regardless of whether the if condition is true or false
It's a shorthand way to write nested if statements
It's used to catch errors in the preceding if statement
