If a semicolon is misplaced in JavaScript, then it may lead to misleading results. Let’s see an example, wherein the if statement condition is false, but due to misplaced semi-colon, the value gets printed.
Example
<!DOCTYPE html> <html> <body> <script> var val1 = 10; if (val1 == 15) { document.write("Prints due to misplaced semi-colon: "+val1); } var val2 = 10; if (val2 == 15) { // this won't get printed document.write(val2); } </script> </body> </html>
