ExperimentalWarning: The ESM module loader is experimental

Node.js has two module systems: CommonJS modules and ECMAScript modules.
Authors can tell Node.js to use the ECMAScript modules loader via the .mjs file extension, the package.json "type" field, or the --input-type flag. Outside of those cases, Node.js will use the CommonJS module loader.

ERROR - This language feature is only supported for ECMASCRIPT6 mode or better: let declaration.

ECMAScript 2015 was the second major revision to JavaScript. ECMAScript 2015 is also known as ES6 and ECMAScript 6.

Issue:

ERROR - This language feature is only supported for ECMASCRIPT6 mode or better: let declaration.
 

Workaround:

The let keyword is not supported to declare a variable. Instead of let try using the var.
