Just a snippet for converting a function as string to code:
Code
<!doctype html>
<html>
<head>
<meta charset=”utf-8″ />
<meta http-equiv=”x-ua-compatible” content=”ie=edge”>
<title>Research</title>
<meta name=”description” content=”A page to quickly spike some code or styling.”>
<meta name=”viewport” content=”width=device-width, initial-scale=1″>
<link rel=”icon” href=”data:;base64,iVBORw0KGgo=”>
<style>
</style>
</head>
<body>
<script>
// Define a function as a string.
// Don’t forget the “(” and the “)” arround the function.
// See: https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/eval
var functionAsString = “(function(a, b){ return a + b; })”;
// Convert a string containing a function definition to a real function.
var fn = eval(functionAsString);
// Execute the created function.
var result = fn(1, 2);
// Log result is: 3
console.log(result);
</script>
</body>
</html>
