title: What is the difference between formik.handleChange and formik.setFieldValue
body: <p>In <a href="https://formik.org/" rel="noreferrer">formik</a>, inside the property <code>onChange</code>, sometimes <code>onChange = {formik.handleChange}</code> is called and sometimes <code>onChange = {v =&gt; formik.setFieldValue('field', v)}</code> is called. Whats the difference between these two?</p>
  <p>Is it possible to replace the use of <code>formik.setFieldValue</code> with just <code>formik.handleChange</code>?</p>
