Go identifiers are used to name program elements including packages, variables, functions, and types. The following summarizes some attributes about identifiers in Go:

  • Identifiers support the Unicode character set
  • The first position of an identifier must be a letter or an underscore
  • Idiomatic Go favors mixed caps (camel case) naming
  • Package-level identifiers must be unique across a given package
  • Identifiers must be unique within a code block (functions, control statements)
