    Ruby supports both && as well as and.


    The basic difference between these 2 lies in their precedence order.

    && has higher preference than and.
    and has lower preference than = unlike && which has higher preference than =

    The major difference comes while evaluating the boolean expressions.


    For ex:-

    as we know = has higher preference than and, so while evaluating the below statement a is assigned as true

    >> a = true and false
    => false
    >> puts a
    true
    

    Now as && has higher preference than =, so firstly the expression is evaluated and then it assigned to a, thus a is set as false

    >> a = true && false
    => false
    >> puts a
    false
