Handlebars: multiple conditions IF statement?

Question

I didn't find this was possible in Handlebars... I need something like this:

{{#if A || B || C}} something {{/if}}

Is that possible to achieve? I have looked at this answer, but as I need for 3 variables (A, B, C) I don't really know how to apply it. Any ideas?

It's the same idea as with 2 parameters. This answer would allow you to use any JS expression. — castletheperson

They do not have multiple conditions. But you can achieve it by nesting. This works:

{{#if A}}
   {{#if B}}
     {{#if C}}
       something 
    {{/if}}
   {{/if}}
{{/if}}

Thanks @BarlasApaydin

this handles {{#if A && B && C}} but not {{#if A || B || C}} really to achieve the "or" scenario it would be {{#if A}}something{{/if}}{{#if B}}something{{/if}}{{#if C}}something{{/if}} but that's not as DRY (don't repeat yourself) because you have to repeat "something" 3 times, where "something" could be a large chunk of code.

how does this answer equivalent to {{#if A || B || C}} something {{/if}} ? isn't it equivalent to {{#if A && B && C}} something {{/if}} ?

What about this?

{{#if A}}
  something
{{else if B}}
  someting B
{{else if C}}
  someting C
{{/if}}

This should be the chosen answer as it gives an alternative solution when the OR-functionality is not implemented in the language

in 3.0 you can do it with

{{#if A}}
  something
  {{else if B}}
    something
    {{else if C}}
      something
    {{/if}}
  {{/if}}
{{/if}}

if you use something below 3.0 you can make multiple ifs

{{#if A}}
{{else}}
  {{#if B}}

... and so on hope this helps
