Use JavaScript to implement a spiral Matrix Algorithm

Spiral matrices need to be used in actual developmentAlgorithm, Using JSCodeImplemented:

VaR Cal = function (LEN) {var helix = [[], [], [], [], [], []; var min = 0; vaR max = len-1; var ROW = 0; var Col = 0; For (VAR I = 0; I <Len * Len; I ++) {helix [row] [col] = I + 1; if (ROW = min & Col <max) {Col = Col + 1 ;} else if (row <Max & Col = max) {ROW = row + 1;} else if (ROW = max & Col> min) {Col = col-1;} else if (row> min & Col = min) {ROW = row-1 ;} if (Row-1 = min & Col = min) {min = min + 1; max = max-1 ;}} return helix ;}; vaR helix = CAL (6); var html = ''; For (VAR I = 0; I  
Algorithm Analysis: First traverse the four outermost edges and then traverse all the edges in them. The traversal algorithm is used to place the edges of values one by one at the specified position.
