//* Array Methods - JavaScript

/* In JavaScript, arrays (or matrices) are objects that can contain multiple elements. Also
They have built-in methods that make it easy to manipulate and manipulate data in arrays. Here
you have some of the most common array methods in JavaScript: */

//? 1. **length:**
// Returns the length (number of elements) of the array.

let numbers = [1, 2, 3, 4, 5];
console.log(numbers.length); // Display 5 in the console

//? 2. **push(element1, element2, ...):**
// Add one or more elements to the end of the array and return the new length of the array.

let fruits = ["apple", "pear"];
fruits.push("orange", "banana");
console.log(fruits); // Display ["apple", "pear", "orange", "banana"] in the console

//? 3. **pop():**
// Removes the last element from the array and returns that element.

let fruts = ["apple", "pear", "orange"];
let lastFruit = fruits.pop();
console.log(lastFruit); // Display "orange" in the console
console.log(fruits); // Display ["apple", "pear"] in the console

//? 4. **unshift(element1, element2, ...):**
// Adds one or more elements to the beginning of the array and returns the new length of the array.

let colors = ["green", "blue"];
colors.unshift("red", "yellow");
console.log(colors); // Display ["red", "yellow", "green", "blue"] in the console

//? 5. **shift():**
// Removes the first element from the array and returns that element.

let colr = ["red", "yellow", "green", "blue"];
let firstColor = colr.shift();
console.log(firstColor); // Display "red" in the console
console.log(colr); // Display ["yellow", "green", "blue"] in the console

//? 6. **indexOf(element, start):**
// Returns the index of the first occurrence of an element in the array or -1 if not found.

let fruit = ["apple", "pear", "orange"];
let index = fruits.indexOf("pear");
console.log(index); // Display 1 in the console

//? 7. **join(separator):**
// Join all elements of the array into a string. You can specify an optional separator.

let number = [1, 2, 3, 4, 5];
let string = number.join("-");
console.log(string); // Display "1-2-3-4-5" in the console

//? 8. **slice(start, end):**
// Returns a part of the array from `start` to `end` (not including `end`).

let numbr = [1, 2, 3, 4, 5];
let slice = numbr.slice(1, 4);
console.log(fragment); // Display [2, 3, 4] in the console

//? 9. **splice(start, deleteCount, item1, item2, ...):**
// Change the content of the array by removing existing elements and/or adding new elements.

let color = ["red", "green", "blue"];
color.splice(1, 1, "yellow", "orange");
console.log(color); // Display ["red", "yellow", "orange", "blue"] in the console

//? 10. **forEach(callback(element, index, array)):**
// Executes a provided function once for each element in the array, in order.

let fru = ["apple", "pear", "orange"];
fru.forEach(function(fru) {
   console.log(fru);
});
// Display "apple", "pear", "orange" in the console
