JavaScript var nums = [1, 11, 3, 2, 5]; for (var i = 0; i < nums.length; i++) { if (nums[i] % 2 === 0) { break; } console.log(nums[i]); } 1 11 3 The loop's header clearly shows that we want to iterate over the entire array. However, inside the loop, the ...
Practical use case: searching an arrayHere's a practical example of using break to optimize a search. main.js const numbers = [4, 9, 15, 6, 2, 12]; let found = false; for (let num of numbers) { if (num > 10) { found = true; console.log(`Found number greater than 10: $...
