how to use if statement in ejs for authenticate links code example

Example 1: if statement in one-line for loop python

>>> [(i) for i in my_list if i=="two"]
['two']

Example 2: how to make comments in markdown which do not render in html

[//] <> (This works, parathesis are necessary btw)
[//] # (This is perhaps the most platform independent solution.
In either case, the comments will not render to html,
even if the user selects view source.)
