Remove element from node.js Buffer

Question

I have a node.js buffer declared in this way;

var buffer_bin;
buffer_bin = new Buffer("ABCDEF", "hex");

Contents of buffer_bin is "ab cd ef" in binary bytes.

I want to remove the first byte ab from buffer_bin such that the contents of buffer_bin becomes "cd ef".

Answer 1

Use the slice method in Buffer object.

 var new_buffer_bin = buffer_bin.slice(1);
