The break keyword is for escaping the switch statement. It then checks whether the first case expression evaluates to the same value as the result of the input. The switch statement tests the value of a variable or an expression against multiple cases, and executes a block of code for the matching case. If its the case that age hold a value of 17 then its code gets executed. A switch statement first evaluates its input expression. Programming often uses it to handle different scenarios and make decisions accordingly. In JavaScript, a switch statement can be used to perform different actions based on different conditions. JavaScript Switch Case Statement : Implementation A switch case statement is a branching structure that allows you to control code execution based on a condition. Conditional statements are an essential part of programming and are used to control the flow of a computer program. It takes a conditional expression just like an if statement but can have many conditionsor casesthat can match the result of the expression to run different blocks of code. One of them may happen if the condition is met.Home Tags Privacy About Javascript - How to use a switch case 21 January 2023 on Javascript report this ad report this ad report this ad The JavaScript switch case is a multiple if else statement. There are three things that can happen in the statement above, but since they are based on conditions, they cannot happen together. The default clause of a switch statement will be jumped to if no case matches the expressions value. And if you don't meet 50, I'll buy you a stick sweet" The switch statement is used to perform different actions based on different conditions. The switch statement evaluates an expression, matching the expressions value against a series of case clauses, and executes statements after the first case clause with a matching value, until a break statement is encountered. If you don't, but you pass 50, I will buy you a toy car. "If you pass 70 score in your exams, I will buy you a bicycle. I'm going to use the example from the referenced article above, for this article also: Switch statements allow you to "switch between" a set of codes to execute depending on the specified conditions. statement by statement) and once JavaScript finds a case clause that evaluates to true, its not only executes. With conditional statements, you execute some code if some conditions are met, and if they are not met, you execute some other code.Īs mentioned in the referenced article above, the two ways for creating conditional statements in JavaScript are if and switch statements. The switch statement executes line by line (i.e.
Sometimes, the flow changes, and this depends on different conditions. Not everything you create in applications is a direct flow. In JavaScript, we can use a switch case to branch out in multiple directions based on different conditions. Do check it out to get the best of this article on switch statements. I made a previous post on if statements explained where I explained what conditionals are in JavaScript.
