Conditional line in handlebars.js with sugar

Question

I am looking to get the following logic in Handlebars.js

• the following line should appear in the output if foo is truthy

  xxx.yyy.zzz = {{foo}}

• no line should appear if foo is falsy

How can I do it?

UPDATE:

• I know I can wrap the line into an #if condition, but it's too wordy, is there a more elegant way?

UPDATE:

• The question is rather:
  • Whether or not Handlebars can handle it without an #if wrap for a single line?
