What makes an empty string in a vue.js template seen as truthy?

How come an empty string in a vue template is considered truthy?

<div>{{ "" ?? "empty string is not truthy" }}</div>

When using the nullish coalescing operator (??), only the empty string will be displayed. Unfortunately, I cannot use this operator to check for empty strings and instead have to resort to ternary operators:

<div>{{ "" ? "string empty" : "string not empty" }}</div>

It seems like "" ?? should be considered falsy, right?

Answer №1

The nullish coalescing operator (??) is used to check if a value is not null or undefined, rather than checking if it is truthy.

An empty string "" is considered falsy, but it is not the same as null or undefined.

To test for truthiness, you can use the Logical OR (||) operator instead.
