Function declarations should not be placed in blocks. Use a function expression or move the statement to the top of the outer function

Question

I have the following code:

if (typeof console === \"object\" && typeof console.error === \"function\") {
    function e(msg) {\"use strict\"; console         


        

Answer 1

You should not be creating function inside if block. You are much better off doing:

var e = function(){};

if(typeof console === "object" && typeof console.error === "function"){
    e = function (msg){ ... };
}
