CCAoA's Symposium brings together leaders from across the child care landscape. filter() calls a provided callbackFn function once for each element in an array, and constructs a new array of all the values for which callbackFn returns a value that coerces to true.Array elements which do not pass the callbackFn test are skipped, and are not included in the new array.. callbackFn is invoked only for array indexes which have assigned values. In this example we use Proxy to toggle an attribute of two different elements: so when we set the attribute on one element, the attribute is unset on the other one..

The reduce() method executes a user-supplied "reducer" callback function on each element of the array, in order, passing in the return value from the calculation on the preceding element.
