// Asynchronous JavaScript basics

// Asynchronous programming is a way to execute code
// without blocking the execution of the rest of the program.

// We commonly use the asynchronous syntax when we need to
// => Get data from another website or API
// => Retrieving / storing data in a database
// => Write / Read files from file system

// COMMON OPERATIONS ON ARRAYS:

// CREATE A NEW VARIABLE
// Array.map => create a new array from an existing array. Each return is a new element of the new array
// Array.filter => create a new array: keeps elements when return true, removes elements when return false
// Array.reduce => create something new (number, string, object, array...) from an existing array. return adds things to the accumulator (acc)

// EXECUTE SIDE EFFECTS
// Array.foreach => Do stuff with each array item (it does not return anything)

// array some helps keeping code succinct when looking for occurences in arrays

const firstArray = ['shark', 'fish', 'dinosaur']
const secondArray = ['whale', 'shark', 'bird']
const thirdArray = ['raptor', 'tuna']

// determine wether 2 arrays have a similar entry
const bool1 = firstArray.some(animal => secondArray.some(otherAnimal => otherAnimal === animal))
console.log("bool1", bool1) // true, "shark" is in both arrays
