Converts the object to a different NumberType equivalent.

#### Type Parameters

##### U

`U` *extends* [`NumberType`](https://docs.bitbadges.io/sdk/reference/type-aliases/number-type)

#### Parameters

##### convertFunction

(`item`) => `U`

##### options?

### equals()

> **equals**\<`U`\>(`other`, `normalizeNumberTypes?`): `boolean`

Defined in: [packages/bitbadgesjs-sdk/src/common/base.ts:147](https://github.com/BitBadges/bitbadgesjs/blob/master/packages/bitbadgesjs-sdk/src/common/base.ts#L147)

Compares this object's fields to another object's fields for equality. Equality is determined by comparing the JSON representations of the objects.

If `normalizeNumberTypes` is true, then all number types will be compared as strings (i.e. "1n" === "1" === 1). Else, they will be compared as their native types (i.e. 1n !== 1 !== "1").

#### Type Parameters

##### U

`U` *extends* [`CustomType`](https://docs.bitbadges.io/sdk/reference/interfaces/custom-type)\<`U`\>

#### Parameters

##### other

##### normalizeNumberTypes?

`boolean`

#### Returns

`boolean`
