I was able to run this code using an online compiler and it provided the right output, which is:

4

0

null

However, I installed JavaScript on Visual Studio and I can't seem to get it to produce the same output. I can see that I can change the "Show output from" to several different options, but none of them give me the output I'm looking for. The Debug option just keeps printing "Hello world."

This is the code:

function simpleSearch(target, arr) {

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

    if (arr[i] === target) {

        return i;

    }

}
return null;

}

// Testing code, calls the function.

console.log(simpleSearch(5, [1, 2, 3, 4, 5])); // Should print 4

console.log(simpleSearch("a", ["a", "b", "c", "d", "e"])); // Should print 0

console.log(simpleSearch(2, ["a", "b", "c", "d", "e"])); // Should print null
