Collect.js - Interview Questions
What is skipUntill() and skipWhile() methods in Collect.js?
skipUntil() : The skipUntil() method skips items until the given callback returns true and then returns the remaining items in the collection:
const collection = collect([1, 2, 3, 4]);

const subset = collection.skipUntil(item => item >= 3);

subset.all();

// [3, 4]
You may also pass a simple value to the skipUntil method to skip all items until the given value is found:
const collection = collect([1, 2, 3, 4]);

const subset = collection.skipUntil(3);

subset.all();

// [3, 4]

skipWhile() : The skipWhile() method skips items while the given callback returns true and then returns the remaining items in the collection:
const collection = collect([1, 2, 3, 4]);

const subset = collection.skipWhile(item => item <= 3);

subset.all();

// [4]
If the callback never returns true, the skipWhile() method will return an empty collection.
 
You may also pass a simple value to the skipWhile:
const collection = collect([1, 1, 2, 2, 3, 3, 4, 4]);

const subset = collection.skipWhile(1);

subset.all();

// [2, 2, 3, 3, 4, 4]
