Nodejs Buffer Memory Leak issue

Excerpt from <node.js advanced Programming >

var buffer = new Buffer ("This is the content of my buffer");

var smallbuffer = Buffer.slice (8,19);

The problem here is that because the sub-buffers are copied from the parent buffer, the parent buffers will not be reclaimed by the garbage collector at the end of the operation, resulting in a memory leak problem;

New node. js version, re-improved the buffer interface, measured without this problem;

New Buffer (array) discarded by: v6.0.0

stability : 0 -obsolete : Use Buffer.from(array) instead.

function Testbuffer () {    var strbuff = "Hello World,hello world,hello world,hello world,hello World,hello World,hello W Orld ";    var arrbuff = new Array;    var buff = Buffer.from (strbuff);        for (var i = 0; i < buff.length; i++) {        arrbuff.push (buff[i]);    };        return buff;}; function Testloop () {    setinterval (() = {        var buff = Testbuffer ();        var Buffson = Buff.slice (1, buff.length-1);        Console.log (Buffson);    }, 1);    }; Testloop ();
