...code. What is this?
Below is some of the coding:
function (B) { var A = 0; try { this.ls$_each(function (D) {B(D, A++);}); } catch (C) { if (C != $break) { throw C; } } return this; }
function (B) { var A = []; this.each(function (D, C) {A.push((B || ls$Prototype.K)(D, C));}); return A; }
function (B) { var A = []; this.each(function (D, C) {if (B(D, C)) {A.push(D);}}); return A; }
function (A) { var B = false; this.each(function (C) {if (C == A) {B = true;throw $break;}}); return B; }
function (A, B) { this.each(function (D, C) {A = B(A, D, C);}); return A; }
