Arrays

First Steps with Arrays from MDN runs through some basic array operations and manipulations.

Iterate through arrays with for..in

let oranges = ['Naval Orange','Tangelo','Clementine','Valencia Orange'];

/* Iterate with for..of */
console.log("Iterate with: item of array");
for (const myorange of oranges) {
   console.log(myorange);
}
console.log("DONE!");

Each array value has an index

let oranges = ['Naval Orange','Tangelo','Clementine','Valencia Orange'];
/*
 oranges[0] is "Naval Orange"
 oranges[1] is "Tangelo"
 oranges[2] is "Clementine"
 etc.
 oranges.length is 4
*/
