Javascript array&string slice function

Comment

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.

The slice JavaScript string method

Comment

// 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
