@abhishekblue So, for every example the return value is:- [ -5, 5 ] even if the input values are different.
This would be primarily because the main.js implementation isn't in-line I'd recommend you to go through it again.
you can also run eslint locally to check for any errors.

@Neerajpathak07 I have checked tests again, also checked by logging the values of the examples it works fine, also checked modules as well. Any other suggestions?

[Neerajpathak07]

@abhishekblue Ig you did everything except giving the main.js file a brief look. since we are testing the values for accumulator function and it is coming inconsistent then definitely the function isn't correct.
