	// Place your snippets for go here. Each snippet is defined under a snippet name and has a prefix, body and 
	// description. The prefix is what is used to trigger the snippet and the body will be expanded and inserted. Possible variables are:
	// $1, $2 for tab stops, $0 for the final cursor position, and ${1:label}, ${2:another} for placeholders. Placeholders with the 
	// same ids are connected.
	// Example:
	// "Print to console": {

/**
 * Return an environment variable typed value from `process.env`.
 * It also supports a default value in case of `undefined`.
 *
 * The function will follow these steps to take a typed value:
 * 1. First it will try to get the env value from `process.env`.
 * 2. Then if `undefined` then it try with the default environment variable value if defined.
 * 3. Otherwise if the default value is `undefined` then it will return the Javascript default values:
 *     - Boolean: `false`
 *     - String: `""`
