//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"

// a negative index can be used to indicate an offset from the end of the array.
//  For example, -2 refers to the second to last element of the array.
