js remove entries from array based on field code example

Example 1: remove item at index in array javascript

// remove element at certain index without changing original
let arr = [0,1,2,3,4,5]
let newArr = [...arr]
newArr.splice(1,1)//remove 1 element from index 1
console.log(arr) // [0,1,2,3,4,5]
console.log(newArr)// [0,2,3,4,5]

Example 2: how can i remove a specific item from an array

const items = ['a', 'b', 'c', 'd', 'e', 'f']
const i = 2
const filteredItems = items.slice(0, i).concat(items.slice(i + 1, items.length))
// ["a", "b", "d", "e", "f"]
