Q207. What is the purpose of uneval - deprecated

[d9k]

Uneval is deprecated and removed from modern browsers:

https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Deprecated_and_obsolete_features#acquiring_source_text

One should use fn.toString() for functions and JSON.stringify() for data.

> function sum(a, b) { return a + b; }
> sum.toString()
'function sum(a, b) { return a + b; }'
