    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

    1. >> a = true and false
    2. => false
    3. >> puts a
    4. 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

    1. >> a = true && false
    2. => false
    3. >> puts a
    4. false
    && and Ruby
