Why should you care?

Shopping carts add prices with +. Login checks password === stored hash. Discount logic uses > and &&.

See it live — copy this example

Paste into an HTML file or the browser console (F12). Use Run below when the live editor is available.

let price = 499;
let qty = 2;
let total = price * qty;
let isFreeShipping = total > 999;
console.log("Total:", total);
console.log("Free shipping?", isFreeShipping);

Run Example »

Edit the code below and click Run to see the result in Toolliyo’s live editor.

What happened?

• * multiplies.
• > compares numbers.
• isFreeShipping becomes true or false (a boolean).
• console.log can print several values separated by commas.

Practice next

1. Run the cart example and note total and isFreeShipping.
2. Change qty to 3 and watch total cross the free-shipping threshold.
3. In the console, compare 5 === "5" vs 5 == "5".
4. Add a discount operator: total * 0.9 when qty >= 3.
5. Use the modulo operator to check if total is divisible by 100.

Remember

Arithmetic: + - * / Comparison: === !== > < Logical: && || !

ScriptVerse cart totals

An e-commerce cart calculates subtotal, tax, and free-shipping eligibility with comparison and arithmetic operators.

Outcome: Correct operator choice prevents wrong prices shown to customers.
