Example 1: javascript get sub array
var fruits = ["Banana", "Orange", "Lemon", "Apple", "Mango"];
var citrus = fruits.slice(1, 3);
// ["Orange", "Lemon"]
Example 2: splice javascript
const months = ['Jan', 'March', 'April', 'June'];
months.splice(1, 0, 'Feb');
// inserts at index 1
console.log(months);
// expected output: Array ["Jan", "Feb", "March", "April", "June"]
months.splice(4, 1, 'May');
// replaces 1 element at index 4
console.log(months);
// expected output: Array ["Jan", "Feb", "March", "April", "May"]
months.splice(0, 1);
// removes 1 element at index 0
console.log(months);
// expected output: Array ["Feb", "March", "April", "May"]
Example 3: javascript slice
//The slice() method extracts a section of a string and returns
//it as a new string, without modifying the original string.
// same in array but you select elements not characters
const str = 'The quick brown fox jumps over the lazy dog.';
console.log(str.slice(31));
// expected output: "the lazy dog."
console.log(str.slice(4, 19));
// expected output: "quick brown fox"
console.log(str.slice(-4));
// expected output: "dog."
console.log(str.slice(-9, -5));
// expected output: "lazy"
console.log(str.slice(0, 2));
// expected output: "the"
// Up to and including the last index!!!
// Different for python.
Example 4: array.slice
const animals = ['ant', 'bison', 'camel', 'duck', 'elephant'];
console.log(animals.slice(2));
// expected output: Array ["camel", "duck", "elephant"]
console.log(animals.slice(2, 4));
// expected output: Array ["camel", "duck"]
console.log(animals.slice(1, 5));
// expected output: Array ["bison", "camel", "duck", "elephant"]
Example 5: slice()
/"slice() copies or extracts a given number of elements to a new array"/
let weatherConditions = ['rain', 'snow', 'sleet', 'hail', 'clear'];
let todaysWeather = weatherConditions.slice(1, 3);
// todaysWeather equals ['snow', 'sleet'];
// weatherConditions still equals ['rain', 'snow', 'sleet', 'hail', 'clear']
Example 6: splice from array
let myFish = ['angel', 'clown', 'mandarin', 'sturgeon']
let removed = myFish.splice(2, 0, 'drum')
// myFish is ["angel", "clown", "drum", "mandarin", "sturgeon"]
// removed is [], no elements removed
