Specifically, the - (minus sign) in {{- and -}} is highly meaningful. It is not just decorative syntax or a continuation of the {{ token; it explicitly clears whitespace. If you aren&rsquo;t careful with these markers, you can quickly ruin the formatting of output that relies on strict whitespace, such as YAML or cleanly indented HTML.
