Description
What happened
Nothing print console[success ? "info" : "error"]("xxxxx")
console[true ? "info" : "error"]("foobar 1") // Not print
;(true ? console.info : console.error)("foobar 2") // Not print
true ? console.info("foobar 3") : console.error("foobar 3") // OKWhat you expected
Should print.
Minimal reproduction
// Main entry point
function main(): void {
const success = true
const log1 = (...args) => {
console[success ? "info" : "error"](...args)
}
log1("[log1] Hello from Perry!")
const log2 = (...args) => {
return (success ? console.info : console.error)(...args)
}
log2("[log2] Hello from Perry!")
const log3 = (...args) => {
return success ? console.info(...args) : console.error(...args)
}
log3("[log3] Hello from Perry!")
console.log()
function dynLog<T>(obj: T, method: keyof T, arg: string) {
typeof obj[method](arg)
}
dynLog(console, "info", "dynLog console['info'] called success")
dynLog(console, "error", "dynLog console['error'] called success")
console.log()
const logger = {

error: (msg: string) => console.error(msg),
}

Fixed (verified twice, independently). All four forms this issue named —
dynLog(console, …),dynLog(logger, …),console[k]andglobalThis.console[k], plusc[k]— are now byte-identical to node.Most likely closed by
ad0be3bf46(changelog.d/10629-computed-key-namespace-member.md), i.e. the #10629 / #10483 computed-key namespace-member work, rather than by anything naming this issue.
