- The same person who pioneered Node JS armed with the hindsight of what would make a better Node JS set out to create Deno.
Deno - Installation
Because Deno is still relatively new, there's only one major version 1.x.x at the time of this writing vs. Node JS versioning which has fifteen major versions.
Note Deno uses a parallel versioning scheme for its standard modules, currently at a sub-1.0 version (e.g. 0.95). Loosely speaking, this shouldn't matter since the Deno intended for wide use and the topic of this tutorial -- dubbed Deno CLI -- is the only version that matters for end users, not to mention a given Deno CLI version is always pegged and compatible against a given Deno standard module version as described in this mapping list.
When it comes to installation, Deno is available for many operating systems either via an installation script or through a package manager, in addition to being available in source code so it can also be built to run on any platform.
In most cases, a few mouse clicks or command line instructions will be sufficient to install Deno. For example, executing
curl -fsSL https://deno.land/x/install/install.sh | sh is enough to install the latest Deno version on your operating system.
Once you successfully install Deno, it will provide a
deno exeuctable that's typically installed on a user's home directory under the
.deno folder inside the
bin sub-directory (e.g. for a user called
admin, the Deno executable will be in
