reset() uses undefined:

vuetify/packages/vuetify/src/mixins/validatable.ts

Lines 205 to 210 in 4cc8b8c

	reset () {
	this.isResetting = true
	this.internalValue = Array.isArray(this.internalValue)
	? []
	: undefined
	},

click:clear uses null:

vuetify/packages/vuetify/src/components/VTextField/VTextField.js

Lines 210 to 213 in 9b354fd

	clearableCallback () {
	this.internalValue = null
	this.$nextTick(() => this.$refs.input.focus())
	},

See also #4144 and #2752

So either this is a bug in the code or in the documentation.

@KaelWD so what about it? ^

[Djaler]

This is still relevant

[Djaler]

With current behaviour it is really ugly to use data with typescript, cause you should consider both undefined and null in type definition

Is anybody here?

@KaelWD So is that the end of it? Why were these both closed as duplicates of each other without explanation?

@KaelWD nevermind, I see #12373 now, thanks :-)
