"It is certain.", "It is decidedly so.", "Without a doubt.", "Yes definitely.",
"You may rely on it.", "As I see it, yes.", "Most likely.", "Outlook good.",
"Yes.", "Signs point to yes.", "Reply hazy, try again.", "Ask again later.",
"Better not tell you now.", "Cannot predict now.", "Concentrate and ask again.",
"Don't count on it.", "My reply is no.", "My sources say no.", The Breakdown:
This section initializes the Alpine.js reactive state. Everything defined here becomes automatically available in the HTML. By setting sensible default values, we prevent the UI from loading in a broken or empty state.
Section 2
"Outlook not so good.", "Very doubtful."

"Het is zeker.", "Het is beslist zo.", "Zonder twijfel.", "Ja absoluut.",
"Je kunt erop vertrouwen.", "Zoals ik het zie, ja.", "Zeer waarschijnlijk.", "Vooruitzicht is goed.",

"Beter je nu niet te vertellen.", "Kan het nu niet voorspellen.", "Concentreer en vraag opnieuw.",

"Vooruitzicht is niet zo goed.", "Zeer twijfelachtig."

},
shake() {The Breakdown:
- This function handles specific business logic for the tool. It mutates the state (variables on `this`), which Alpine.js immediately detects, causing the HTML UI to re-render the changes instantly.
Section 3
if (this.question.trim() === '') {
alert(this.$data.lang === 'nl' ? 'Stel eerst een vraag!' : 'Ask a question first!');
return;
}
this.isShaking = true;
this.answer = null;
setTimeout(() => {
let pool = this.answers[this.$data.lang] || this.answers['en'];
this.answer = pool[Math.floor(Math.random() * pool.length)];
this.isShaking = false;
}, 800);
}The Breakdown:
- We utilize
Math.random()here to introduce randomization. This is the core engine of the game's unpredictability, allowing us to pick random elements. - Notice the use of
setTimeout. While JavaScript can calculate results instantly, adding a slight artificial delay creates suspense and makes the application feel like a physical game.
