Why Are Dashes Used in Go Template Conditionals?

The Purpose of Dash in Go Templates' Conditional Statements

In Go templates, a dash is frequently used in conditional statements, such as {{- if ...}}, like the example provided:

{{- if hasKey .Values.mymap "mykey" }}
    # do something conditional here...
{{- end }}

This dash serves a specific purpose: it removes spaces from the output on the side of the template where it appears. According to the official documentation:
