nonce in script tag

<!-- nonce (meaning) :  coined for one occasion. e.g. "a nonce word" -->
<!--e.g  <script nonce="EDNnf03nceIOfn39fn3e9h3sdfa">…</script> -->

nonce attribute is way to tell browsers the inline contents of a particular
script or style element weren’t injected into the document by some (malicious) 
third party, but were instead put in the document intentionally by whoever 
controls the server the document is served from.
