String vs extracted variable in React shallow test

I am having the following simple unit test in React:

const prop = {name: '::name::'}
const wrapper = shallow(<Component prop={prop} />)

expect(wrapper.equals(
    <div>
        <div>::name::</div>
    </div>
)).toEqual(true)

And I am wondering if it is correct to extract the name variable and check the expected rendered result against it:

const name = ::name::
const wrapper = shallow(<Component prop={name: name} />)

expect(wrapper.equals(
    <div>
        <div>{name}</div>
    </div>
)).toEqual(true)

I suppose <div>::name::</div> is better than <div>{name}</div>, but I need arguments why, anyone? :}
