Question about arrays and include method

I need help to list the items in an array that makes the include method true.
I have this so far

return newArray

i’ve beenm struggling to find out how to list the new array with onlythe items inside tthe array with the same string as the input string

for example.
array=[ chocolate cake, chocolate fudge, vanilla, banana]
string =choc olate
return i’m looking for
newArra=[chocolate cake, chocolate fudge];

You could use filter:

const array = ['chocolate cake', 'chocolate fudge', 'vanilla', 'banana'];
const string = 'chocolate';
const newArray = array.filter((item) => item.includes(string));
