To find the largest number in a JavaScript array using a program, you can use the `Math.max()`

method, which returns the largest of zero or more numbers:

```
var numbers = [1, 2, 3, 4, 5];
var largest = Math.max(...numbers);
console.log(largest); // Output: 5
```

In this example, `Math.max()`

is called with the spread operator `...`

to spread the elements of the `numbers`

array into separate arguments. The result of the `Math.max()`

call is the largest number in the `numbers`

array.

Alternatively, you can loop through the array and keep track of the largest number so far:

```
var numbers = [1, 2, 3, 4, 5];
var largest = Number.NEGATIVE_INFINITY;
for (var i = 0; i < numbers.length; i++) {
if (numbers[i] > largest) {
largest = numbers[i];
}
}
console.log(largest); // Output: 5
```

In this example, `largest`

is a variable that keeps track of the largest number found so far. The `for`

loop iterates through each element in the `numbers`

array, and the `if`

statement checks whether the current element is greater than the largest number found so far, and updates `largest`

if it is.
