NS interface

Collection of all functions passed to scripts

Signature:

export interface NS 

Remarks

Basic usage example:

export async function main(ns) {
 // Basic ns functions can be accessed on the ns object
 ns.getHostname();
 // Some related functions are gathered under a sub-property of the ns object
 ns.stock.getPrice();
 // Most functions that return a promise need to be awaited.
 await ns.hack('n00dles');
}
