Usually, operator is function that takes two values and return a value, and used in infix form, since in haskell infix and prefix form is interchangable, so you can define operator as function taking two arguments.<div><br>

</div><div>&gt;&gt;&gt; 1+2</div><div>3</div><div>&gt;&gt;&gt; (+) 1 2</div><div>3</div><div>&gt;&gt;&gt; map (+1) [1,2,3]</div><div>[2,3,4]</div><div>&gt;&gt;&gt; (+1) `map` [1,2,3]</div><div>[2,3,4]</div><div><br></div>

<br>
In a book that I am reading the author distinguishes between &quot;operator&quot; and &quot;function.&quot;<br>
<br>
Example: The &quot;+&quot; is an operator. The &quot;map&quot; is a function.<br>
<br>
What&#39;s the difference between operator and function?<br>
