Whether two values are equal or not can be decided by the == operator, for example, 5 == 5 and 5 == 5.0 are both true. Equivalent to this operator is the isequal() function:
isequal(5, 5) #> true isequal(5, 5.0) #> true
Both the preceding statements return true, because objects such as numbers are immutable and they are compared at the bits level.
To see whether the two objects x and y are identical, they must be compared with the === operator. The result is a Bool value, true or false: x === y -> Bool, for example:
5 === 5 #> true 5 === 5.0 #> false
For objects that are more complex, such as strings, arrays, or objects that are constructed from composite types, the addresses in the memory ...
