Arithmetic logic support

[szeredaiakos]

Suggestion

Should be self-explanatory. But:

In short:
aNumber += (a<b) * 12 - (a>=b) * 14
Is significantly faster than:
if (a<b) { aNumber += 12} else {aNumber -= 14}

The first method ends up in error yet most major languages and runtimes handle it correctly.

This is not self-explanatory at all, we're not mind readers. And TypeScript officially has no spec, so there's nothing to update.

A wild guess is be that you want #26382.

It is unrelated.
Apparently is not so explanatory. Updating...

Unfortunately you still didn't fill out the issue template after updating. :-(

From that brief example it now looks like a duplicate of #27501. This is intentionally not supported: #27501 (comment)

It works fine if you add an explicit type conversion using Number(), which also makes your intent much clearer in the code.

Yes, casting is competitive, not quite the same tho. We may not argue about the clarity of code which uses logic arithmetic :).
Yes, thx, Martin!
Yes, this is a copy of #27501
