seek() equivalent in javascript/node.js? -

i m trying read files fs module node.js. since lack tot of function m used (fseek(), getline()...), m creating module them back. (a node.js copy of c stdio.h).

my simple question is:

does seek() exist in other name or need remplement every function have it?

in node.js seek , read functions one. when use fs.read function, there parameter called position, works "seek position".

if want write file, function fs.write has position parameter.

check docs here: https://nodejs.org/api/fs.html#fs_fs_read_fd_buffer_offset_length_position_callback
