doesntContain()
: The doesntContain() method determines whether the collection does not contain a given item. You may pass a closure to the doesntContain method to determine if an element does not exist in the collection matching a given truth test:
const collection = collect([1, 2, 3, 4, 5]);
collection.doesntContain(value => value < 5);
// false
const collection = collect([1, 2, 3]);
collection.doesntContain(4);
// true
You may also use doesntContain on object based collections:
const collection = collect({
name: 'Free Time Learn',
number: 12,
});
collection.doesntContain('Free Time Learn');
// false
collection.doesntContain('Darwin Núñez');
// true
You may also pass a key / value pair to the contains method, which will determine if the given pair exists in the collection:
const collection = collect({
name: 'Free Time Learn',
number: 11,
});
collection.doesntContain('name', 'Darwin Núñez');
// true
