How to break/continue across nested for each loops in TypeScript

Question

I tried to use break inside nested for each loop and it says jump target cannot cross function boundary. please let me know how can i break nested for each loop when certain condition is met in TypeScript.

groups =[object-A,object-B,object-C]     groups.forEach(function (group) {     // names also an array         group.names.forEach(function (name) {              if (name == 'SAM'){          break; //can not use break here it says jump target cannot cross function boundary       }          }          } 

Answer 1

forEach accepts a function and runs it for every element in the array. You can't break the loop. If you want to exit from a single run of the function, you use return.

If you want to be able to break the loop, you have to use for..of loop:

  for(let name of group.names){     if (name == 'SAM') {       break;     }   } 

Answer 2

ForEach doesn't support break, you should use return

  groups =[object-A,object-B,object-C]         groups.forEach(function (group) {         // names also an array             group.names.forEach(function (name) {              if (name == 'SAM'){              return; //           }      }    }
