nl_tokens: * @method randomize () @returns Array @short Returns a copy of the array with the elements randomized . @extra Uses Fisher - Yates algorithm . @example
pl_tokens: function ( ) { var arr = this . concat ( ) , i = arr . length , j , x ; while ( i ) { j = ( math . <mask> ( ) * i ) | 0 ; x = arr [ -- i ] ; arr [ i ] = arr [ j ] ; arr [ j ] = x ; } return arr ; }
