In all languages that support an operator
:= it means assignment.
- In languages that support an operator
=operator usually means an equality comparison.
- In languages where
==is typically used for equality comparison.
I can’t recall any languages where
:= means the same as
= are both used for assignment, however they are not interchangeable and selecting the correct one depends on the context. To make matters more confusing the
= operator is also used for comparison. The interpretation of
= as either assignment or comparison also depends on context.
