Hop and JavaScript == Description == This tutorial shows how HOP client side programs and JavaScript programs can interact. This tutorial shows that since Hop and JavaScript share * the global variables, * the global functions, * the same data structures, they can be blended without restriction. In other words, the interoperability between HOP and JavaScript is total. == Blending Hop and JavaScript == HOP and JavaScript can easily interact. HOP can call JavaScript functions and use JavaScript variables and vice versa. Hence, a HOP program can simultaneously use HOP and JavaScript. ~~ HOP and JavaScript may exchange values (read and write) without restriction. Each language can also set the global variable of the other language. ~~ HOP client-side expression are introduced by the ,(

 "~") character.
JavaScript expressions are enclosed in angle brackets (,( "{...}")).
