check if object values contains string node js

let exists = Object.values(obj).includes("test1");

check if an object contains a value in javascript

var obj = { a: 'test1', b: 'test2' };
if (Object.values(obj).indexOf('test1') > -1) {
   console.log('has test1');
}

js does object contain value

// You can turn the values of an Object into an array.
// Then test that a value is present:

// This assumes, that the Object is not nested
// and the value is an exact match:

var obj = { a: 'test1', b: 'test2' };

// Note that an array can only have positive index's; so
// checking for a negative index is a super valid way for getting a
// boolean value as a result for the check.
if (Object.values(obj).indexOf('test1') > -1) {
   console.log('Value exists!');
}
