Search Array of strings for matching character sequence

April 24, 2022

I have an array like this

const arr = ["Apple", "Banana", "Cherry", "Orange", "Avocado", "Ananas", "Pineapple];

I need a function that returns an array with all the Elements from arr, that match the given character sequence. The order of the characters is of importance.

Given "ppl" the function should return ["Apple", "Pineapple"].

Given "n" the function should return ["Banana", "Orange", "Ananas", "Pineapple"].

Given "voca" the function shoould return ["Avocado"]

Given "rr" the function should return ["Cherry"], while given a "r" the function should return ["Cherry", "Orange"].

>Solution :

try this

const arr = ["Apple", "Banana", "Cherry", "Orange", "Avocado", "Ananas", "Pineapple"];


const search = query => arr.filter(s => s.toLowerCase().includes(query))

console.log(search("n"))
console.log(search("ppl"))
