[i if i is True else 'nope' for i in [True, False, True]]

# [True, 'nope', True]

# Notice this is a conditional expression and different from list comprehension
# Which typically is `for ... if ...`
# Now it's reversed and no expression for truthy condition `if x <condition> else <expression>`

/*
* One of the questions that recently came up is how to remove vowels from Hebrew characters in Unicode
* (or any other similar language). A quick look at Hebrew Unicode chart shows that the vowels are all
* located between 0x0591 (1425) and 0x05C7 (1479). With this and Javascript's charCodeAt function, it
* is trivial to strip them out with Javascript as follows
*
* Live demo is available here:
