Handelbars.js Cumulative / Sum Helper

Hello. Do you mean something like this? {{#each_sum items id="item-table" sum-on="price" sum-placeholder="csum"}} <span>{{name}} | Price: {{price}}, Cumulative: {{csum}}</span> {{/each_sum}} <div>Total: {{sum items sum-on="price"}}</div> With example input of the form: { items: [ { name: "ItemA", price: 5.99 }, { name: "ItemB", price: 4.99 }, ], } It would output: <div> <ul sum-placeholder="csum" sum-on="price" id="item-table"> <li><span>ItemA | Price: 5.99, Cumulative: 5.99</span></li> <li><span>ItemB | Price: 4.99, Cumulative: 10.98</span></li> </ul> </div> <div>Total: 10.98</div> If so, let me know - I'm new to the platform, so I would like to help you out with this to gain some reputation. I've already tried the example I've sent, so if that functionality is satisfactory, I can send you the code very soon. The way I went about it: #each_sum helper: - I defined a custom block helper that iterates over the list and maintains a running total - the sum-on="price" hash argument lets you define on which property to sum - the sum-placeholder="csum" hash argument is optional, defaults to csum, and it lets you specify where in the template below should the cummulative sum appear. sum helper: - just a regular custom helper that uses the sum-on="price" hash argument to determine on which property to sum
