serializeForScript() function

Serialize a value as a JavaScript expression that is safe inside an inline<script>. Use it for server state inlined into HTML, such as aroot.dehydrate() payload:

const html = `<script>window.__OLAS_STATE__ = ${serializeForScript(root.dehydrate())}</script>`

The result is JSON.parse("…") over the JSON, with every character that could end the string, the script or an attribute written as a \uXXXX escape. Two reasons for JSON.parse over a plain object literal: - a key named __proto__ stays an own property, where an object literal would make its value the object's prototype; - U+2028 and U+2029 cannot reach the script source raw.

Throws what JSON.stringify throws, for a BigInt or a cycle.
