I am looking an equivalent of http://commons.apache.org/proper/commons-lang/apidocs/org/apache/commons/lang3/StringUtils.html#isBlank(java.lang.CharSequence)
I found several 3rd party extensions, but is there one out of the box with underscore.js: http://underscorejs.org

Following @muistooshort's advice I created my mixin and wanted to share it:



  _.mixin({

    isBlank: function(string) {

      return (_.isUndefined(string) || _.isNull(string) || string.trim().length === 0)

    }

  });



> _(t).isBlank()

< true



> _(qwerty).isBlank()

< false
