If none of the if or else if conditions pass, then JavaScript moves forward and doesn't run any of the conditional blocks of code.

The throw statement throws a user-defined exception. Execution of the current function will stop (the statements after throw won't be executed), and control will be passed to the first catch block in the call stack. If no catch block exists among caller functions, the program will terminate. The conditional (ternary) operator is the only JavaScript operator that takes three operands: a condition followed by a question mark (?), then an expression to execute if the condition is truthy followed by a colon (:), and finally the expression to execute if the condition is falsy. This operator is frequently used as a shortcut for the if statement. Therefore, you write else followed by what you want to occur, surrounded by curly braces.

Use else to specify a block of code to be executed, if the same condition is false. Use else if to specify a new condition to test, if the first condition is false.

Check a password between 6 to 20 characters which contain at least one numeric digit, one uppercase ... When the break statement is used with a switch statement, it breaks out of the switch block. This will stop the execution of more execution of code and/or case testing inside the block. When the break statement is used in a loop, it breaks the loop and continues executing the code after the loop (if any). The break statement can also be used ...
