Does nodejs have to be installed on the c drive?

Node.js is an open source runtime environment that can run JavaScript code. It can run on different operating systems, such as Windows, Linux and Mac OS X, etc. When we install Node.js, we usually choose to install it on the C drive by default, but this does not mean that Node.js must be installed on the C drive. On Windows systems, the C drive is the partition where the system is located. This is also where the system usually installs software by default. Since Node.js is an open source software, when downloading and

nodejs package loading process

Node.js is a Javascript running environment based on event-driven, non-blocking I/O. It allows us to organize and manage code more conveniently through an integrated modular system. In Node.js, modularization is an important concept. Each file is treated as an independent module, and these modules can be loaded through the require function. In Node.js, the module loading process is mainly divided into three steps: path analysis, file location and compilation execution. Below we will introduce the process and working principle of these three steps in detail. path
