Let's parse a function expression with
jscodeshift.template.expression
:This code is a valid expression, but not a valid statement -- a function needs to have a name to be a valid statement.
template.expression
surrounds the code with()
to force parsing as expression. However, it fails to do so if the template string doesn't have any interpolation parameters. Therefore, the above function expression fails to parse.This PR fixes that bug -- the length of the
template
array is incorrectly checked. It should check forlength === 1
instead oflength === 0
. Moreover, a special case forlength === 1
is not even necessary.
