In July 2017 I wrote about ways to execute JavaScript snippets from your clipboard using process substitution. The snippet that I’m using since then to execute JavaScript snippets quickly is the following…
$ node <(pbpaste)
Today I came across a tweet by Julian Gruber and it turns out you use the pipe operator with the Node.js binary directly.
$ pbpaste | node
The result is the same but it looks nicer and feels better that using process substituion (<(...)
). I have no idea how I missed this Node.js detail and checked the previous versions of Node.js and it works going down to Node.js v4
(that’s what I have available on my machine). Good to know!
