how to check if an object has at least one true value

Question

I have an array that looks like following

values = {de: true, en: false, nl: false, pl: false, ru: false}

I using the array to make a layout change in jsx, how can I check if the array has at least one true value in JSX,

any help would be appreciated.

Your "array"'s syntax is invalid. Arrays do not have key-value pairs. — CertainPerformance, Oct 11 '19 at 07:25
And during your research you haven't found a solution for this task (after fixing the syntax of the array)? — Andreas, Oct 11 '19 at 07:28

Assuming that values is actually an object, check if .some of the Object.values of the object are true:

const values = {de: true, en: false, nl: false, pl: false, ru: false};

const someTruthy = Object.values(values).some(val => val === true);
console.log(someTruthy);

(if the only truthy value is true, you can use (val => val) instead)

Cool shorthand with `val => val` but I would honestly stick with `val => val === true` even if the only truthy value is `true` as it's more clear to future readers (including yourself!) – Joshua Pinter Jul 11 '23 at 17:32
