Break for loop from inside of switch case in Javascript

Question

What command I must use, to get out of the for loop, also from //code inside jump direct to //code after

//code before for(var a in b)     {     switch(something)         {         case something:             {             //code inside             break;             }         }     } //code after 

Answer 1

You can use label. Have a labeled statement and break to that label. outerLoop is the label I have used here.

//code before outerLoop: for (var a in b) {     switch (something) {         case 'case1':             //code inside             break outerLoop;     } } //code after 

Answer 2

use another variable to flag when you need to exit:

var b = { firstName: 'Peter', lastName: 'Smith' };  var keepGoing = true;  for (var a in b) {    switch (true) {      case 1:        keepGoing = false;        break;    }    if (!keepGoing) break;    console.log('switch end');  }  console.log('for end');
