Break loop once condition match JavaScript

const arr = [1,2,3]; 

Iterations loops:

for 

every() 

some()

We can use:

for(let item of arr){ 

 console.log(item);

 if(item == 2){

     break; 

 } 

}

Or

for (var i = 0; i < arr.length; i++) { 

 console.log(arr[i]); 

 if (arr[i] === 2) {

       break;

  } 

}

Or

arr.every((elm) => { 

 console.log(elem); 

 if (elm === 2) {

       return true;

 }

 return false;

});

Or 

arr.every((elm) => { 

 console.log(elem); 

 if (elm === 2) {

       return false;

 }

 return true; 

});
