php array_slice code example

Example 1: javascript slice array

// array.slice(start, end)
const FRUITS = ["Banana", "Orange", "Lemon", "Apple", "Mango"];
var citrus = FRUITS.slice(1, 3);
// citrus => [ 'Orange', 'Lemon' ]

// Negative values slice in the opposite direction
var fromTheEnd = FRUITS.slice(-3, -1);
// fromTheEnd => [ 'Lemon', 'Apple' ]

Example 2: javascript copy array

var oldColors=["red","green","blue"];
var newColors = oldColors.slice(); //make a clone/copy of oldColors

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.
