JavaScript String Concatenation

Here’s a periodic reminder that JavaScript supports string concatenation with a plus sign:

> 'foo' + 'bar'
'foobar'

This simple solution works just as well as the alternatives:

// .join (common solution, in my experience)
> ['foo', 'bar'].join('')
'foobar'

// .concat
> 'foo'.concat('bar')
'foobar'

// Interpolation
> `foo${'bar'}`
'foobar'

A plus sign is all you need.
