Is this specific JavaScript function classified as recursive?

Uncertain about the recursive nature of this function.

var capitalizeWords = function(input) {
    var results = [];

    if(typeof input === 'string'){
            return input.toUpperCase();
    }else{
        input.forEach(function(word){
            results = results.concat(capitalizeWords(word));    
        });
    }
    return results;
};

//converts all words in the array to uppercase

Answer №1

Affirmative, however it is not a direct recursion but rather an indirect recursion.

The recursive process occurs within an anonymous higher order function, not the actual function itself.

Answer №2

Indeed, this is a recursive function.

output = output.concat(capitalizeFirstLetters(word));
