-@param expect an array of key => value
-with the key being name of the variable, like this :
-  'my_var' => 'value',
-simpler way to do it is to use compact when calling the function :
-  add_var_to_front(compact("var1", "var2", "var3"));
+pass variables to front as global variables, accessible in js as an object
+@param two params :
+1. an array of key => value
+   with the key being name of the variable, like this :
+    'my_var' => 'value',
+   simpler way to do it is to use compact when calling the function :
+    add_var_to_front(compact("var1", "var2", "var3"));
+2. name of first embended script (if we want to have the variables
+   availables to all js : it will be available to the script and all following)
+	 - default value is "init", assuming the first script is called "init.js"
+old version :
+- was using wp_add_inline_script() which is rather for scripts than variables
+- it had to write explicitly the variable declaration as "const myvar = 'value'"
