The slice JavaScript string method

// You use this method to cut out a substring from an entire string.
// We will use this method to cut out the remaining part of a word (excluding the first letter):

const word = "freecodecamp"

const remainingLetters = word.substring(1)
// reecodecamp

// slice from index 2 to end
let str1 = str.slice(2);
console.log(str1);

// slice from index 1 to index 8
let str2 = str.slice(1, 8);
console.log(str2);

// slice from index 5 to index (str.length - 3)
let str3 = str.slice(5, -3);
console.log(str3);

// slice from index 100 to end (returns '')
let str4 = str.slice(100);

yes i can

array slice a string

console.log(Array.prototype.slice("abcdefghijklmnopqrst"))
/*console.log an empty array*/

Javascript array&string slice function

const a=[1,2]
//const b=a
//above line makes b point to same object in heap as a

To create a copy of a we can write this instead:
const b=a.slice()
// b now contains it's own object [1,2] in heap

Note:slice method is similar(but a little different) to slice operator in python
For ex. unlike slice operator(python), js slice method only accepts 2 arguments.

javascript string slice

let x = ["a", "b", "c", "d", "e", "f"];

console.log(Array.prototype.slice.call("abcdefg"))
/*[ 'a', 'b', 'c', 'd', 'e', 'f', 'g' ]*/
/*slice can turn a string into an array with its letters as elements*/

string slice

a="grayorphanvillain"
t=a[0:-13:1]
print(t,'/',end=" ")
k=a[-13:-7:1]
print(k,'/',end=" ")
m=a[-7:]
print(m,end=" ")
#output:
gray / orphan / villain
