unicorn/consistent-empty-array-spread Pedantic

💡 A suggestion is available for this rule.

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.

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

Examples of incorrect code for this rule:

javascript

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

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

Examples of correct code for this rule:

javascript

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

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