Gentlemen, good day to all. There is a task to sort out JSON in Handlebars.

It is necessary, it turns out, to output, in a separate block, each object array -> [0], [1] containing arrays with data
I was tormented to look for how to draw a conclusion by indexes.
Did it like this:

{{#each array}}
        {{#each this}}
            {{@index}} {{this}}
        {{/each}}
{{/each}}

Answer 1

Did it like this:

{{#each array}}
        {{#each this}}
            {{@index}} {{this}}
        {{/each}}
{{/each}}

What is array? There is no such property in json. Write this.
