    String Operators Redirect 1

    Summary

    In addition to the comparison operators, which can be used on string values, the concatenation operator (+) concatenates two string values together, returning another string that is the union of the two operand strings. For example, "my " + "string" returns the string "my string".

    The shorthand assignment operator += can also be used to concatenate strings. For example, if the variable mystring has the value "alpha", then the expression mystring += "bet" evaluates to "alphabet" and assigns this value to mystring.

    var mystring = "tooth";
    var yourstring = "brush";
    var ourstring = mystring + yourstring;
    console.log(ourstring) // Prints "toothbrush"
    var mystring = "alpha";
    console.log(mystring += "bet"); // Prints "alphabet"
