Is there a way in handlebars JS to incorporate logical operators into the standard handlebars.js conditional operator? Something like this:
{{#if section1 || section2}} .. content {{/if}} I know I could write my own helper, but first I'd like to make sure I'm not reinventing the wheel.

The logical OR ( || ) operator (logical disjunction) for a set of operands is true if and only if one or more of its operands is true. It is typically used with boolean (logical) values. When it is, it returns a Boolean value.
To iterate over an object with JavaScript and Handlebars. js, we can use the #each keyword. to add the Handlebars script and the template for looping through each entry in data . We use #each this to loop through each array property.
To call JavaScript function from Handlebars, we can register a helper. to add a template that uses the printItems helper. Then we create the printItems helper and use it by writing: Handlebars.
This is possible by 'cheating' with a block helper. This probably goes against the Ideology of the people who developed Handlebars.
Handlebars.registerHelper('ifCond', function(v1, v2, options) { if(v1 === v2) { return options.fn(this); } return options.inverse(this); }); You can then call the helper in the template like this
{{#ifCond v1 v2}} {{v1}} is equal to {{v2}} {{else}} {{v1}} is not equal to {{v2}} {{/ifCond}} If you love us? You can donate to us via Paypal or buy me a coffee so we can maintain and grow! Thank you!
