What steps will reproduce the bug?

Just write:

node -e "console.log(encodeURIComponent('price$100'))"

and output will be:

price00

instead of:

price%24100

as it works in browser (any chromeish and code in MDN)

It works strangely when $ sing in encoded string. Sometimes like abowe it cuts aftercharacter with it, sometimes it cuts all string as for example in:

node -e "console.log(encodeURIComponent('$a100'))"

it prints nothing.

encodeURI() function behaves same.

May be here is some nodejs specifics about this function?

How often does it reproduce? Is there a required condition?

always

What is the expected behavior? Why is that the expected behavior?

'$' sign converts to '%24'

What do you see instead?

nothing (empty string)

Additional information

Wrote in "steps to reproduce section".

Found only #33799 issue where stated that encodeURIComponent in nodejs works as in ecmascript standart.

node -e "console.log(encodeURIComponent('price$100'))"

Have you tried running this directly in REPL? This is almost certainly your shell interpolating $1 within a double-quoted string, and nothing to do with Node.js.

Yeah this has nothing to do with Node.js 22.x, only the shell you're using

$ node -p "encodeURIComponent('price$100')"
price
$ node -p 'encodeURIComponent("price$100")'
price%24100
$ node -v
v22.20.0

AFAICT this is working as expected, closing

Thanks for mentioning shell! My fail. $ was interpreted as name of shell variable :)
