Understanding how validateLab1.js works

Hi,

Can someone please help me understand below piece of code from validateLab1.js

while (result != 1) {
data++
result = result % 2 === 0 ? result / 2 : result * 3 + 1
}

Thanks in Advance,
Naresh

No. The formula is there so that you are not able to guess the validation code.

Hi @NareshKumar_Kota,

This javascript file contains the code to verify your aggregation pipeline.
This is the first lab in the course and the count is provided in order to debug the pipeline. Therefore we use validator file to find the correct answer which is not the count of aggregation pipeline output.

You can refer to the following link to understand the Javascript expressions and operators:

Please feel free to reach out if you have any questions.
