Does use of anonymous functions affect performance?
What are performance implications (if any) on parse and run-time when using function expression vs declaration in Javascript?
For example, what are performance characteristics and differences of the following two ways:
var functionOne = function() {
// Some code
}
or:
function functionTwo() {
// Some code
}
NOTE: The question is not about whether it is faster to declare function but about function execution.
