Determine whether an array contains a value [duplicate] (18 answers)

Closed 3 months ago.

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.

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)
