Use markdown formatting:

Expected: '1\n1*2\n1**3', instead got: '1\n1*2\n1**3\n'

Note: There is no newline in the end (after the pattern ends)

Expected: '1\n12\n1**3', instead got: '1\n12\n1**3\n'

You must return the result, not print it.

That's a problem with your code, print the input to analyze why it fails. Read this: https://docs.codewars.com/training/troubleshooting/#print-input

Not a kata issue.

SyntaxError: Unexpected end of JSON input

at JSON.parse (<anonymous>)

at findOutlier (test.js:21:17)

at Context.it (test.js:56:25)

As you can see from the message, you return a NaN, but the expected value is an integer (105313274). Are you sure you initialize your variables correctly? For example let myValue instead of let MyValue = 0.
