The following statement is made in the pick ax book:
We’ll use the # character in the string to interpolate the value of
these instance variables.
“Song: #@name–#@artist (#@duration)”
If I had been doing what they appear to be doing, I would have enclosed
the respective variable names in braces. I’m sure that they are trying
to tell me something by omitting the braces; but, I’m not sure what. In
fact, without the braces, I don’t see how it even works. Can someone
please clarify for me how they are able to omit the braces and the
significance of doing so? Thanks for any input.
