海外TECH	DEV Community	Understanding Switch Statement In Javascript	https://dev.to/ayabouchiha/understanding-switch-statement-in-javascript-40i9	Understanding Switch Statement In JavascriptHello I m Aya Bouchiha today we re going to discuss switch statements in Javascript The switch is a statement used to perform different operations based on multiple conditions cases Writing a switch statementswitch expression case value do something break case value do something break case value do something break default do something if the varaibale does not match any case we need to know that if the variable matches multiple cases the code block of the first matched case will be executed case we use it to match against an expression If it matches the code block of this case will be executed If It is not The default code block will be executed default is used to perform some operations if the variable does not match any case of the specified cases break optional is a statement associated with each case that orders the program to breaks out of the switch statement Example const country Morocco switch country case USA console log Washington break case Morocco console log Rabat break case Egypt console log Cairo break case Spain console log Madrid break case France console log Paris break default console log your country is not in our list on this code above the program will log Rabat because the given country is equal to Morocco RabatExample Let s delete all break statements const country Morocco switch country case USA console log Washington break case Morocco console log Rabat break case Egypt console log Cairo break case Spain console log Madrid break case France console log Paris break default console log your country is not in our list Output RabatCairoMadridParisyour country is not in our listWe observe that the code blocks of the matched case which is Morocco and the rest cases including the default one are executed due to forgetting to write break statements Example Let s remove break statements that are only inside Morocco s and Egypt s case Let s see what will happen const country Morocco switch country case USA console log Washington break case Morocco console log Rabat break case Egypt console log Cairo break case Spain console log Madrid break case France console log Paris break default console log your country is not in our list Output RabatCairoMadridWe observe that the code blocks of Morocco s and Egypt s cases are executed because of not writing a break statement conclusion If the break statement is not written the code block of the matched case and the rest cases including the default one will be executed until the program finds a break statement Example If we wrote the same code of example and we replaced Spain s break statement with a return statement the program will log the same thing const country Morocco switch country case USA console log Washington break case Morocco console log Rabat break case Egypt console log Cairo break case Spain console log Madrid return case France console log Paris break default console log your country is not in our list Output RabatCairoMadrid Conclusion break statement is not required if the code block contains a return statement Example const price switch price case console log you have to pay break case console log you have to pay break case console log you have to pay break default console log I don t know Output you have to pay In this example the program logged you have to pay because the price is Let s do a small change by replacing the price cases with a string without changing the value just adding a double or single quote const price switch price case console log you have to pay break case console log you have to pay break case console log you have to pay break default console log I don t know Output I don t know We observe that the code block of the default case is executed instead of the third case code block due to changing the datatype conclusion Switch cases use strict comparison which is So the cases values should be the same type of the given expression SummarySwitch statement use strict comparison case we use it to match against an expression If it matches the code block of this case will be executed If It is not The default code block will be executed default is used to perform some operations if the variable does not match any case of the specified cases break optional is a statement associated with each case that orders the program to breaks out of the switch statement In addition a break statement is not required if the code block contains a return statement If the break statement is not written the code block of the matched case and the rest cases including the default one will be executed until the program finds a break or a return statement Hope you enjoyed reading this post Suggested PostsYoutube Courses Projects To Learn JavascriptYou Complete Guide To Set Object In JavascriptAll JS String Methods In One
