Interrupt array Foreach method [js implementation]

Realization principle

There is no built-in method to implement interrupts forEach, If we want to implement interrupts forEach, We can do this by throwing an exception .

Implementation code

var BreakException = {};

try {
  [1, 2, 3].forEach(function(el) {
    console.log(el);
    if (el === 2) throw BreakException;
  });
} catch (e) {
  if (e !== BreakException) throw e;
}
