This a great question but I think it's simple to understand.
1. break
- Use to exit Switch command when finishing a condition
var i = 10; switch(i) { case 10: // code block break; case 9: // code block break; default: // code block }- Use to exit a loop (for/while..)
for(var i = 0; i<=100; i++){ if(i % 8 == 0){ break; // stop loop and read commands below loop } } // Some code here2. continue
Only use in the loop when you want to skip a step loop and continue loop next step.
string text = ""; for(var i = 0; i<=100; i++){ if(i % 5 == 0){ continue; // stop curent step loop and start next step of loop } text = text + i + " "; } alert(text);3. return
Only used for the function to return value of that function. It also exists loops and Switch command
function(a, b){ if(a > b){ return a + b; } return a *b; }I hope this info helpful to you.
