Check object for certain value using lodash

Question

I want to check if a certain property has a certain value using lodash. The code below prints out false. How can I check the value correctly?

code example

const ob = {
 archived:true,
 done: true
}

console.dir(_.includes(ob.archived, true));

You need to use _.includes directly with the object, here's an example of that:

const ob = {archived:true};

_.includes(ob, true); // true

If you have to check for a single value only you can use this:

const ob = {archived:true, done: true};

_.includes(_.pick(ob, ['archived']), true); // true

You can use _.matchesProperty(). The method generates a function, that accepts an object, and returns true if the object contains the stated property and value.

const hasArchivedTrue = _.matchesProperty('archived', true)

const ob = {
 archived: true,
 done: true
}

console.log(hasArchivedTrue(ob)) // true
console.log(hasArchivedTrue({})) // false
