"build": "rm -rf ./build && mkdir ./build && ./node_modules/.bin/babel -d ./build ./src"
This is the command in package.json and it gives me an error saying:
rm is not recognized as internal or external command.
Invalid switch /build

That script was written for the UNIX shell, which does not work on windows. The correct way to do this in a cross-platform way is to use rimraf & mkdirp.
Also, the ./node_modules/.bin/babel portion could be shortened to simply babel (./node_modules/.bin/babel doesn't work on windows IIRC).
Properly written, the script should be:
"build": "rimraf ./build && mkdirp ./build && babel -d ./build ./src"
For this script to work, you will have to install rimraf and mkdirp. You can do this by running:
npm install --save-dev rimraf mkdirp
The --save-dev flag will add rimraf and mkdirp to your package.json's devDependencies section so that they will automatically be installed with future npm installs.

In order to run bash commands on Windows you need to install Bash complied for Windows. Install Cygwin and add bin directory to you PATH variable.

Windows 10 does not provide a UNIX shell by default. You'll need the appropriate UNIX utilities (such as rm) and a shell that supports the syntax you specified.
You have a few options:
Use the Windows 10 Bash Shell - Recent versions of Windows 10 now provide beta support for running Ubuntu within Windows without requiring a virtual machine.
Use Cygwin for development - Cygwin provides a shell of your choice and plenty of UNIX / Linux utilities.
Run a Virtual Machine with a Linux Guest - There are many options for running a VM on Windows. You can use Hyper-V, VirtualBox, or VMware Player. For a guest operating system, Ubuntu is a popular choice, but Fedora and Debian are also common alternatives.

Use rd /s /q "folder name" instead of rm -rf "folder name"
回答5:
Not to Bash, but in Windows you can use the built-in remove directory (rd) command:
RD /S /Q "folder-name"
