RANDOM ANSWER PROJECT

A simple vanilla js based app, that return a random answare

Description

Experimenting the DOM Manipulation, i have coded this very simple app, with the only one goal: to modify a string in the DOM with a random path of words. This project take just a few minuts to code, is very simple but it gives the foundaments for the DOM Manipulation.

Concepts

To code this, I have used just two functions, the first one is the randomWord(), taht just one paramether, an array:

function randomWord(array) {
    return Math.floor(Math.random() * array.length);
}

The goal of this function is very simple: it takes an array as argument, and return a random index of it.

The second function is the generateAnswer(), a function with no return value that is connectet to the onclick event in HTML button.

function generateAnswer() {
    let answer = `${subject[randomWord(subject)]} ${verb[randomWord(verb)]} ${object[randomWord(object)]}`;
    display.innerText = answer;
}

This one, just create a variable with a template literal, that construct the answer using the randomWord() for each of the arrays.
