JavaScript template engine in just 20 lines

• var template = 'Hello, my name is <%name%>. I\\'m <%age%> years old.';

  I\\'m =>I\'m

• var re = /<%([^%>]+)?%>/g;

  Maybe [^%><] would be better?

The final implementation has errors：

1.

line.replace(/"/g, '\\\\"') + '");

this code syntaxError: missing ) after argument list

change:

line.replace(/"/g, '\\"') + '");

2. last line code to update

  return new Function(code.replace(/\\r|\\t|\\n/g, '')).apply(options);
