  1. In JavaScript, strings are not arrays so you can do something like this:

    str[2] = ‘d’;

    But you cannot do this.

  2. Is there a missing “not” in this sentence: “In JavaScript, strings are not arrays so you can do something like this:

    str[2] = ‘d’;”

  3. In the above example, both references (str1 and str2) are equal because they point to the same object (‘abc’).

    I would change this phrase and also the image it is confusing… because in the end they are not pointing to the same object abc.. they have different values.. so no matter if you change str1 , str2 wont be affected. Because strings are primitive not references.. therefore there;s no pointing.
