Experiment with adding and removing the minus sign at the end of the ERb <%= %> sequence (i.e., changing %> into -%>, and vice versa. what will be the difference

2

Putting a - sign at the end (like -%>) means that no new line will be inserted into the template in the final output.

For example:

<%= 'hello' -%> there

Will result in "hello there"

<%= 'hello' %> there

Will result in: "hello\n there"
