Tests

Function name is findLongestString
findLongestString(["one","two","three"])	Expected:	"three"
findLongestString(["lorem","ipsum","dolor","sit","amet"])	Expected:	"lorem"
findLongestString([])	Expected:	""

Solution

Here's how I would approach this, but keep in mind there might be other ways to solve this problem.

function findLongestString (array: string[]): string {
    let longest = '';
    for (let i = 0; i < array.length; i++) {
        if (array[i].length > longest.length) {
            longest = array[i];
        }
    }

    return longest;
}
