Arrays 2 : Static Methods Array.of() Array.from() Array.isArray() Object.entries() Object.keys() Object.value()

Array.of() Array.from() Array.isArray() Object.entries() Object.keys() Object.value()

// Array.of(); // Make an array from its arguments

// Array.of('Wes', 'Kait');

// Make an array from a String or Iterable.

// How to create a Range from x to y:

function createRange(start, end) {

const range = Array.from({ length: end - start + 1}, function(_item, index) {

return index + start;

})

return range;

}

// Make a function that creates a range from x to y with Array.from();

const myRange = createRange(3, 7424);

// Check if the last array you created is really an array with Array.isArray();

console.log(Array.isArray(myRange));

// Take the meats object and make three arrays with Object.entries(), Object.keys, Object.values()

// console.log(Object.entries(meats));

// console.log(Object.keys(meats));

// console.log(Object.values(meats));

//This one is already destructured:

Object.entries(meats).forEach(([key, value]) => {

// const key = entry[0];

// const value = entry[1];

// const [key, value] = entry;

 console.log(key, value);
