Phân biệt Truthy và Falsy trong JavaScript và các trường hợp dễ nhầm lẫn?

February 15, 2026

Quick summary

In JavaScript, falsy values are those that coerce to `false` when evaluated in a boolean context, consisting of exactly 8 specific values. All other values (including empty arrays `[]` and empty objects `{}`) are truthy.

Sample answer:

Lorem ipsum dolor sit amet, consectetur adipiscing elit. Sed do eiusmod tempor incididunt ut labore et dolore magna aliqua. Ut enim ad minim veniam.

Quis nostrud exercitation ullamco laboris nisi ut aliquip ex ea commodo consequat. Duis aute irure dolor in reprehenderit in voluptate velit esse cillum dolore.
