unnecessary_ brace_ in_ string_ interps
Avoid using braces in interpolation when not needed.
Details
#AVOID using braces in interpolation when not needed.
If you're just interpolating a simple identifier, and it's not immediately
followed by more alphanumeric text, the
{}
can and should be omitted.
BAD:
print("Hi, ${name}!");
GOOD:
print("Hi, $name!");
