Returns the length of the given string or array.

Params

  • value {Array\|Object\|String}
  • returns {Number}: The length of the value.
    • default

    Returns the first value that is not undefined, otherwise the "default" value is returned.

    Params

  • value {any}
  • defaultValue {any}
  • returns {String}
    • eq

    Block helper that renders a block if a is equal to b. If an inverse block is specified it will be rendered when falsy. You may optionally use the compare="" hash argument for the second value.

    Params

  • a {String}
  • b {String}
  • options {Object}: Handlebars provided options object
  • returns {String}: Block, or inverse block if specified and falsey.
    • gt

    Block helper that renders a block if a is greater than b.

    If an inverse block is specified it will be rendered when falsy. You may optionally use the compare="" hash argument for the second value.

    Params

  • a {String}
  • b {String}
  • options {Object}: Handlebars provided options object
  • returns {String}: Block, or inverse block if specified and falsey.
    • lt

    Block helper that renders a block if a is less than b.

    If an inverse block is specified it will be rendered when falsy. You may optionally use the compare="" hash argument for the second value.

    Params

  • context {Object}
  • options {Object}: Handlebars provided options object
  • returns {String}: Block, or inverse block if specified and falsey.
    • lte

    Block helper that renders a block if a is less than or equal to b.

    If an inverse block is specified it will be rendered when falsy. You may optionally use the compare="" hash argument for the second value.

    Params

  • a {Sring}
  • b {Sring}
  • options {Object}: Handlebars provided options object
  • returns {String}: Block, or inverse block if specified and falsey.
    • gte

    Block helper that renders a block if a is greater than or equal to b.

    If an inverse block is specified it will be rendered when falsy. You may optionally use the compare="" hash argument for the second value.

    Params

  • a {String}
  • b {String}
  • options {Object}: Handlebars provided options object
  • returns {String}: Block, or inverse block if specified and falsey.
    • ternary

    Returns either of the two values provided based on the condition given.

    Params

  • Condition {Boolean}
  • trueValue {String \| Number}
  • falseValue {String \| Number}
  • returns {String \| Number}
    • isnt

    Block helper that renders a block if a is not equal to b. If an inverse block is specified it will be rendered when falsy.

    Params

  • a {String}
  • b {String}
  • options {Object}: Handlebars provided options object
  • returns {String}
    • not

    Returns true if val is falsey. Works as a block or inline helper.

    Params

  • val {String}
  • options {Object}: Handlebars provided options object
  • returns {String}
    • or

    Block 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.

    Params

  • arguments {...any}: Variable number of arguments
  • options {Object}: Handlebars options object
  • returns {String}: Block, or inverse block if specified and falsey.
    • and

    Helper that renders the block if both 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.

    Params

  • a {any}
  • b {any}
  • options {Object}: Handlebars provided options object
  • returns {String}
    • startsWith

    Params

  • prefix {String}
  • testString {String}
  • options {String}
  • returns {String}
    • ellipsis

    Truncates a string to the specified length, and appends it with an elipsis, (…).
