Nullish Coalescing vs Walrus Operator: Modern Operator Face-Off

JavaScript ?? operator vs Python := walrus operator. Which language's modern operator is more useful? This comparison is INSANE!

Encapsulating the atrocity of umask handling with Python's walrus operator:

os.umask(current_umask := os.umask(0))

This isn't clearly *better*, but at least it's clearly shorter. Without `:=`, we'd need two lines:

current_umask = os.umask(0)
os.umask(current_umask)

Note: The awkwardness is a necessary consequence of how POSIX handles umask. Also, neither version is threadsafe.

#Python #WalrusOperator #umask

would you use the #WalrusOperator?

 if test_fit(i, j, s) or test_fit(i, j, s := 1):
    fill_grid(i, j, s)

or make it a bit longer like this

if test_fit(i, j, s):
    fill_grid(i, j, s)
elif test_fit(i, j, 1):
    fill_grid(i, j, 1)
