let story = “The dog ran away, The cat is unhappy,cat watched the sky and saw adog”
result should be :
return dog cat cat dog notice the last one on the story string is “adog” not a “dog” we just want to return the value whenever the dog combination appears.

how to return a specific combination of characters in a string when they are surrounded by other characters.

Answer

You can use regular expressions, using the | to separate the strings to search for.

The match() method retrieves the result of matching a string against a regular expression.

let story = "The dog ran away, The cat is unhappy,cat watched the sky and saw adog" 

const search = /dog|cat/g;

console.log(story.match(search));

// will result in ["dog", "cat", "cat", "dog"]
