How to find specified words in an array?

Question

Arrays

hello everyone, I have a question about the task.
There are two inputs.
In the first input, the user enters a string, let's say "tacked tacked but didn't catch".
In the second input, the user enters "la".
Using the button should display words that contain "la", that is, "tacked tacked tacked"

Answer 1

Pseudocode:

input1 = "лавировали лавировали да не вылавировали"
input2 = "ла"

array = input1.split(" ")

result =""

for (i = 0; i < array.length; i++) {
   if (array[i].includes(input2)) {
        result += array[i]
   } 
}

return result

Answer 2

Split a string into words and check for a substring in each
