<p>
Strings can be concatenated using the <code>+</code> operator
or the <code>+=</code> assignment operator:
</p>

<pre>
s := "hi" + string(c)
s += " and good bye"
</pre>

<p>
String addition creates a new string by concatenating the operands.

    *   Added a `tf.keras.layers.experimental.preprocessing.HashedCrossing`
        layer which applies the hashing trick to the concatenation of crossed
        scalar inputs. This provides a stateless way to try adding feature
        crosses of integer or string data to a model.
    *   Removed `keras.layers.experimental.preprocessing.CategoryCrossing`.

   * Returns a hash function which computes its hash code by concatenating the hash codes of the

   * specific length.
   *
   * <p>For example, if you need 1024-bit hash codes, you could join two {@link Hashing#sha512} hash
   * functions together: {@code Hashing.concatenating(Hashing.sha512(), Hashing.sha512())}.
