Render yes or no:

  {{lte a b yes='yes' no='no'}}

and: And operator

And operator. This is a boolean operation.

Truthiness of arguments is determined by isEmpty, so this helper can be used with non-boolean values.

Multiple arguments are supported too:

  {{#and a b c d}}
    yes
  {{else}}
    no
  {{/and}}

Render yes or no:

  {{#and a b}}
    yes
  {{else}}
    no
  {{/and}}

Render true or false:

  {{and a b}}

Render yes or no:

  {{and a b yes='yes' no='no'}}

or: Or operator

Or operator. This is a boolean operation

Truthiness of arguments is determined by isEmpty, so this helper can be used with non-boolean values.

Multiple arguments are supported too:

  {{#or a b c d}}
    yes
  {{else}}
    no
  {{/or}}

Render yes or no:

  {{#or a b}}
    yes
  {{else}}
    no
  {{/or}}

Render true or false:

  {{or a b}}

Render yes or no:

  {{or a b yes='yes' no='no'}}

not: Not operator

  {{not a}}

Render y or n:

  {{not a yes='yes' no='no'}}

cmp: Compare operator

Compare to object as Comparables.

Renders 1 if a > b, 0 if a == b -1 if a < b

  {{cmp a b}}

isNull: Compare operator

Test if one element is null.

  {{isNull a}}

isNotNull: Compare operator

Test if one element is not null.

  {{isNotNull a}}
