Fillter in an array
const words = ['spray', 'limit', 'elite', 'exuberant', 'destruction', 'present'];
const result = words.filter(word => word.includes('e'));
console.log(result);
// expected output: Array ["elite", "exuberant", "destruction", "present"]But if an array consists of many arrays inside, I am not finding a reasonable way to solve it.
Example: with this array
const array = [
["aaaa", "b", "c", "d", "e", "f", "g"],
["h", "i", "j", "k", "l", "m", "n"],
["haaaa", "i", "j", "k", "laaaa", "m", "naaaa"],
["o", "o", "o", "o", "o", "o"],
];
How to fillter ‘a’ and get result
result = [
["aaaa", "b", "c", "d", "e", "f", "g"],
["haaaa", "i", "j", "k", "laaaa", "m", "naaaa"],
];
>Solution :
Use filter and some
const data = [
["aaaa", "b", "c", "d", "e", "f", "g"],
["h", "i", "j", "k", "l", "m", "n"],
["haaaa", "i", "j", "k", "laaaa", "m", "naaaa"],
["o", "o", "o", "o", "o", "o"],
];
const output = data.filter((arr) => arr.some((item) => item.includes("a")));
console.log(output);
