Comparing .includes(), .filter(), and .some() in JavaScript.js

const SIZE_OF_ARRAY = 10
const anArray = Array.from(Array(SIZE_OF_ARRAY + 1).keys())
anArray.shift()
console.log(anArray) // Array(10) [ 1, 2, 3, 4, 5, 6, 7, 8, 9, 10 ]

const SEARCH_VALUE = SIZE_OF_ARRAY / 2 // i.e. 5

anArray.includes(SEARCH_VALUE) // true
anArray.filter((x) => x === SEARCH_VALUE).length > 0 // true
anArray.some((x) => x === SEARCH_VALUE) // true

let foundIt = false
for (let index = 0; index < anArray.length; index++) {
  if (anArray[index] === SEARCH_VALUE) {
    foundIt = true
    break
  }
}

console.log(
  `anArray.includes(${SEARCH_VALUE}) is ${anArray.includes(SEARCH_VALUE)}`
)
console.log(
