node.js - Confused about nodejs versions and javascript versions -

when install nodejs download following file:

node-v5.5.0-x64.msi

however, when run "node -v"

 v0.12.2

i downloaded tutorial code on nodejs , see use new javascript "let" statement instead of old "var" keyword.

however, when try execute javascript code in tutorial, not work until change "let" "var".

then works.

(1) version of nodejs did download? v0.12 or v5?

(2) should support new "let" statement?

(3) there different version can download supports "let" statement?

thanks

what you're looking @ in filename not node.js' version or npm's version, release version of installer bundle.

if you're having path issues, as seems are, can let node update itself:

npm update node npm update npm

and make version in path latest version.

otherwise can edit environment variables manually:
