If you forget to add breaks to your switch cases, you will enter the matching case plus all the cases beneath it. var x = 2; switch(x){ case 1: document.write("1"); case 2: document.write("2"); case 3: document.write("3"); } //outputs "23"

so how can you execute only certain cases, for example i have list of 5 cases and i want to execute only those that are true. if i keep break in every case, there will be only one result, if i remove all breaks, there will be more results than it was supposed to be. or maybe for this example i should use else if?

It simply go for all the code unnecessarily though the program will be unaffected and it print after the first condition true switch, then all one by one.
