JSLint good or bad!???

Question

JavaScript

In general, I don’t know what to do ... here and so you are trying to write code ... so it also gives you errors during validation ...
in short, here is a code example ...

function say(){

    return function (name){
    return greet + " " + name;
    };
}

var greet = 'Hello';
var en = say();
console.log(say("John"));
console.log(say("Martin"));

and here is the fucking validator www.jslint.com
How to write such code without errors??

Answer 1

And what is there to explain?) look at the code, there is svg, which changes its path when hovering over

Answer 2

Do not write kaku and everything will be ok, in the same place in the output it is written what is wrong. And this is not a "fucking validator", but a VERY effective system for straightening crooked arms.

Answer 3

Well, you have everything written as it should:

/*global console*/
var greet = 'Hello';
function say() {
    "use strict";
    return function (name) {
        return greet + " " + name;
    };
}

var en = say();
console.log(say("John"));
console.log(say("Martin"));
