A shorthand for writing 2-tuples. Very commonly used when expressing key/value pairs in CSS or Json encoders.

Swaps the elements in a pair.

swap ( 1, 2 ) == ( 2, 1 )

The maximum safe value for an integer, defined as 2^53 - 1. Anything larger than that and behaviour becomes mathematically unsound.

(maxSafeInteger + 1) == (maxSafeInteger + 2)
    == True

The minimum safe value for an integer, defined as -(2^53 - 1). Anything smaller than that, and behaviour becomes mathematically unsound.

(minSafeInteger - 1) == (minSafeInteger - 2)
    == True

Checks if a given integer is within the safe range, meaning it is between -(2^53 - 1) and 2^53 - 1.

isSafeInteger 5 == True
isSafeInteger maxSafeInteger == True
isSafeInteger (maxSafeInteger + 1) == False
