Why is javascript written in width [duplicate]

Question

Why do programmers write javascript like this?

function(e){function n(r){if(t[r])return t[r].exports;var o=t[r]={i:r,l:!1,exports:{}};return....

Not like that

function(e) {
    function n(r) {
        if (t[r]) return t[r].exports;
        var o = t[r] = {
            i: r,
            l: !1,
            exports: {}
        };
        return```
