I have found a way to set strict mode in node.js.
--use_strict
option is enabled in node.js runtime.
If this option enable, the program become strict mode inspite of "use strict";
or not.
Thank you for your contribution. Did the generated code run under strict mode?
IMO we should better always set use strict
in the generated code, but I am not confident enough that it would not introduce any compatibility problem nor have any impact on execution speed.
FYI The code generated by JSX is not compatible with strict mode. You can see some tests failing in branch: https://github.com/jsx/JSX/tree/kazuho/experiments/use-strict
@kazuho
As tested your branch on my environment (v0.11.11), I don't see any warning or test failures. Which test case did you see failing?

Sorry.
You need to run JSX_RUNJS='node --use_strict' make test
on the aforementioned branch (kazuho/experiments/use-strict
).
I have fixed subtle issues re compatibility with strict mode, but there are still problems.
I published a JSX module implements
Object.freeze
in yesterday.https://github.com/yosuke-furukawa/freezer.jsx
However,
Object.freeze
do not throw exception in non-strict mode.I would like to know how to set 'use strict' in JSX.
