and

Helper that renders the block if all of the given values are truthy. If an inverse block is specified it will be rendered when falsy. Works as a block helper, inline helper or subexpression. In the following example t1,t2 variables are true and f1 is false.

Block expression:

{{#and t1 t2 t3}}
will be rendered
{{else}}
(optional): will be shown when and is false
{{/and}}

Subexpression:

{{#if (and t1 t2 f1)}}
will not be rendered (because f1 is false)
{{/if}}

or

Helper that renders a block if any of the given values is truthy. If an inverse block is specified it will be rendered when falsy. Works as a block helper, inline helper or subexpression. In the following example t1 variable is true and f1, f2 are false.

Block expression:

{{#or f1 f2 t1}}
will be rendered
{{else}}
(optional): will be shown when or is false
{{/or}}

Subexpression:

{{#if or(f1 f2 t1)}}
will be rendered
{{else}}
(optional): will be shown when or is false
{{/or}}

not

Returns the inverse boolean of the provided value. I.e. it returns false when the provided expression is true and vica versa. Works as block expression or inline expression:

Block expression:

{{#not t1}}
Not rendered
{{/not}}

Inline expression:

{{#if (not (compare a ">" b))}}
Shown if a is less or equal than b
{{/not}}
