unicorn/consistent-empty-array-spread Pedantic

💡 A suggestion is available for this rule.

What it does

When spreading a ternary in an array, we can use both [] and '' as fallbacks, but it's better to have consistent types in both branches.

Why is this bad?

Having consistent types in both branches makes the code easier to read and understand.

Examples

Examples of incorrect code for this rule:

const array = [a, ...(foo ? [b, c] : "")];

Examples of correct code for this rule:

const array = [a, ...(foo ? [b, c] : [])];

const array = [a, ...(foo ? "bc" : "")];
