FAQ
Questions mustache owners ask.
- 01
Why Mustache instead of Handlebars or EJS?
Mustache has a universal spec. the same template renders identically in JS, Python, Go, Ruby, Rust, and 30+ languages. Handlebars and EJS are JavaScript-only. If your pipeline spans multiple languages, Mustache is the only portable choice.
- 02
Is it safe to render user-provided templates?
Yes. Mustache is logic-less. templates can only insert data, never execute code. There's no eval(), no function calls, no file access. Intrinsically safe by design.
- 03
Can it iterate over lists and arrays?
Yes. Mustache sections ({{#items}}...{{/items}}) iterate over arrays automatically. Each item's properties are accessible inside the section.
