Functions

Built-In Functions in JetClient provide powerful tools for tasks such as random value generation, user input, file operations, JavaScript execution, and more.
Functions can be used within Inline Expressions or evaluated in scripts.

Using Functions

• Functions start with a $ sign.

• Some functions require arguments, while others do not.

• Functions without arguments can omit parentheses:
  Examples:

  • {{$randomEmail}} or {{$randomEmail()}}
  • {{$randomInt(1, 10)}}

• You can nest and chain functions for complex logic:
  Example: {{$pickOne(["admin", "user"]) + "@" + $randomDomainName}}
