Handlebars custom if else helper

gistfile1.txt

Handlebars.registerHelper('isMobile', function(conditional, options) {
                if(conditional)
                  return options.fn(this)
                
                return options.inverse(this);
            });
            
            
Example:
Handlebars.registerHelper('isMobile', function(conditional, options) {
    var fnTrue=options.fn, fnFalse=options.inverse;
    return $('html').hasClass('touch') ? fnTrue(this) : fnFalse(this);

});
            
Use it as such:
 {{#isMobile this}}
  <img src="{{image1}}"/>
  {{else}}
  <img src="{{image2}}"/>
  {{/isMobile}}
  
Passing in "this" allows it to use the same context as the rest of the template.
