Filter an array with elements by first letter of each word

Question

I have this code :

return !this.form.get('skills').value.map(item => item.id).includes(skill.id) &&
            (value === null || skill.name.toLowerCase().startsWith(value.toLowerCase()));

I have this liste :

Artist
Armagedon
Commandos Artist
Refactor
Gol Jumir Afart
Armony

If I write : A : I get the liste :

Artist
Armagedon
Armony

But I want to get and items : Commandos Artist and Gol Jumir Afart.

Can you help me please ?

Answer 1

You can use a Regexp in order to filter your values. We are going to look for every words starting by your letter.

const myFilter = 'A';

const regex = new RegExp(`(^${myFilter}.*)|( ${myFilter}.*)`, 'i');

const filtered = [
  'Artist',
  'Armagedon',
  'Commandos Artist',
  'Commandos Artist Paul',
  'Refactor',
  'Gol Jumir Afart',
  'armony',
].filter(x => regex.test(x));

console.log(filtered);
