JavaScript Array Type

Iteration

We can loop through all the elements of an array by using the forEach method. This method takes a function parameter and calls it once for every element in the array. It does not cause the array to mutate. The callback function should accept a value from the array.

Copy
const quote = [
  "A",
  "man",
  "can",
  "only",
  "stumble",
  "for",
  "so",
  "long",
  "before",
  "he",
  "either",
  "falls",
  "or",
  "stands",
  "up",
  "straight.",
]

quote.forEach(word => {
  console.log(word.toUpperCase())
})

The example above calls the console.log function on every element in the array.
