# Key points
- The spread operator can be applied to strings to spread them into an array containing each character as a separate item.
- Iteration methods loop through every value in a collection and apply an operation to each value.
- JavaScript has a number array of methods that apply a callback to every item in the array.
- The `forEach()` method applies the code in the callback for every item in the array.
- The `map()` method returns a new array by applying the code in the callback to every item in the array.
- The `reduce()` method returns a single value by applying an accumulator function defined in the callback to every value in the array—for example, adding up all the values in the array.
- The `filter()` method returns a new array containing only the values from the original array that match the criteria defined in the callback.
- The `find()` method returns the first item in an array that matches the criteria given in the callback.
- The `every()` method returns `true` if every item in the array matches the criteria given in the callback. Otherwise, it returns `false`.
- The `some()` method returns `true` if any item in the array matches the criteria given in the callback. It returns `false` if none of the items in the array match the criteria.
- We can iterate over objects using a `for–in` loop that will give us access to each property in the object.
- The `Object.keys()`, `Object.values()` and `Object.entries()` methods will return an array of an object’s keys, values, or key–value pairs respectively.

After the quiz and challenge, we’ll be getting functional with functions.
