Although these two statements might appear to be equivalent, they are not, due to the order of operations. Specifically, the and and or operators have lower precedence than the = operator, whereas the && and || operators have higher precedence than the = operator, based on order of operations.

To help clarify this, here’s the same code, but employing parentheses to clarify the default order of operations:

(val1 = true) and false # results in val1 being equal to true val2 = (true && false) # results in val2 being equal to false
