I like the idea, but I don't uunderstand the purpose of accumulating errors. Why we can't throw them if validation fails without accumulating?

@ivan-tymoshenko @mcollina is there anything else missing to get this merged? |

Why not use cause and avoid the Object.assign?
| else throw Object.assign(new TypeError(\`The value of '${schemaRef}' does not match schema definition.\`), { | |
| validationErrors: errors | |
| }) | |
| else throw new TypeError(\`The value of '${schemaRef}' does not match schema definition.\`, { | |
| cause: errors | |
| }) |

could this be faster?

This would be then:
| t.same(err.validationErrors, [ | |
| t.same(err.cause, [ |
| t.fail('should throw') | ||
| } catch (err) { | ||
| t.equal(err.message, 'The value of \'#/properties/data\' does not match schema definition.') | ||
| t.same(err.validationErrors, [ |

i think the rationale here was to call it as fastify with ajv implementation:

I hope my remarks make sense :)

when using a schema that includes
anyOforoneOfand it fails to find a match the error is pretty worthless (in my case it is usually'The value of \'#\' does not match schema definition.')and it is not trivial to debug since stack trace points to anonymous functions composed at runtime.
this sets the validation errors on the error before throwing it. if the performance penalty is too big I suggest it should be behind a
