Array Prototype Functions

.cycle()

Returns an object with useful helper methods for stepping through the array with .next() and .previous()..

Usage

Step 1:

Assign an array

let array = [1, 2, 3, 4];

Step 2:

Assign a new variable to store the cycle object.

let arrayCycle = array.cycle();

Step 3:

Start the cycle

NOTE: Without providing arguments the cycle starts at the first index of the array. You can optionally pass in a starting index.

arrayCycle.start(); 

Optionally takes a starting index.

.start(1)

Step 4: Cycle by calling either next() or previous() methods.

arrayCycle.next();

Example

let arrayCycle = ['John Smith', 'Chris Johnson', 'Mike Henry', 'Amy Michelle'].cycle();
arrayCycle.start(1);
arrayCycle.next();
arrayCycle.previous();
