PrependTo

  • PrependTo[ s , elem ] prepends elem to the value of s, and resets s to the result.
  • PrependTo[ s , elem ] is equivalent to s = Prepend[ s , elem ].
  • PrependTo[ s , elem ] does not evaluate s.
  • You can use PrependTo repeatedly to build up a list.
  • See the Mathematica book: Section 2.4.4.
  • See also: AppendTo.

    Further Examples

    This prepends the number 44 to the beginning of the list.

    In[1]:=

    Out[1]=

    In[2]:=

    Out[2]=

    The original list is changed as a side effect.

    In[3]:=

    Out[3]=

    On the other hand, Prepend does not change the new version of the list.

    In[4]:=

    Out[4]=

    In[5]:=

    Out[5]=

    In[6]:=
