The stats.atimeNs property is an inbuilt application programming interface of the fs.Stats class is used to get the timestamp when the file is accessed last time since the POSIX epoch expressed in nanoseconds. Syntax:

stats.atimeNs;

Parameters: This property does not have any parameter, but during creation of stats object {bigint:true} must be passed as options. Return Value: It returns a number or BigInt value that represents the timestamp when the file is accessed last time since the POSIX epoch expressed in nanoseconds. Below examples illustrate the use of stats.atimeNs property in Node.js: Example 1: Output:

Using stat: 1592654526560650
Using lstat: 1592664546730291

Example 2: Output:

Using stat synchronous: 1592664546730291

Note: The above program will compile and run by using the node filename.js command and use the file_path correctly. Reference: https://nodejs.org/api/fs.html#fs_stats_atimens
