The break keyword tells the interpreter that the code inside any. If you noticed in the above syntax, every case ended with the break keyword. Although, it a good programming practice to terminate the last case or default clause in a switch statement with a break. The switch case statement takes an expression inside the parenthesis and then it checks that expression for different cases and executes the particular code or the statements associated with that case. If another case statement is added to the switch statement, it prevents a possible programming error later. It is a more organized and concise alternative to using multiple if-else statements. In the case of the default clause, the break statement is not required when it finally appears in a switch statement. The JavaScript switch statement is a way to make decisions in your code based on different conditions. The break keyword is for escaping the switch statement. Like other curly braced, C based languages, your JavaScript can benefit from a switch statement. If its the case that age hold a value of 17 then its code gets executed. I use this statement often, especially in my nodejs AWS Lambdas, where my business heavy logic resides. The break statement will tell the JavaScript interpreter to break out of the switch…case statement block once it executes the code with the first true case. The switch case statement may trip up even the most seasoned JavaScript developer. To stop this, you must add a break statement after each case. In JavaScript, we can use a switch case to branch out in multiple directions based on different conditions. It then checks whether the first case expression evaluates to the same value as the result of the input. The JavaScript once find a case clause that evaluates to true, it does not only run the code corresponding to that case clause, but it also executes all the subsequent case clauses till the end of the switch block automatically. A switch statement first evaluates its input expression. The switch statement executes statement by statement or line by line. In one crucial way, the Switch…case is different from the if…else statement. In JavaScript, the switch statement is used to execute code based on the value of an expression.
