javascript slice / splice

const numbers = ['1', '2', '3', '4', '5'];

​

console.log(numbers.slice(2));

// expected output: Array ["3", "4", "5"]

​

console.log(numbers.slice(2, 4));

// expected output: Array ["3", "4"]

​

console.log(numbers.slice(1, 5));

// expected output: Array ["2", "3", "4", "5"]

​

​

numbers.splice(1, 0, '1.5');

// inserts at index 1

console.log(numbers);

// expected output: Array ["1", "1.5", "2", "3", "4", "5"]

​

numbers.splice(4, 1, '4.5');

// replaces 1 element at index 4

console.log(numbers);

// expected output: Array ["1", "1.5", "2", "3", "4.5", "5"]

​

numbers.splice(4, 2);

// removed "4,5", "5"

console.log(numbers);

// expected output: Array ["1", "1.5", "2", "3"]
