You can just do:
['truck', 'car', 'people'].reduce((text, word) => `${text}-${word}`) > "truck-car-people"
If no initial variable is given (your first example had '') then it just pulls from the input, in this case, 'truck'
''
'truck'
You (obviously) need an initial value if the array is empty or you get a very descriptive error:
[3, 2.1, 5, 8].reduce((total, number) => total + number, 0) > 18.1 [3, 2.1, 5, 8].reduce((total, number) => total + number) > 18.1 [].reduce((total, number) => total + number, 0) > 0 [].reduce((total, number) => total + number) > VM158:1 Uncaught TypeError: Reduce of empty array with no initial value
