🌉 FE Algorithm Review 01

Goal: Replace "it" to "aa"

function myReplaceAll(str, substr, replacement) {
  return str.split(substr).join(replacement)
}

//value
myReplaceAll(
        'Lorem ipsum dolor sit amet, consectetur adipiscing elit.',
        'it',
        'aa'
      )

---

.split()

const aaa = 'Lorem ipsum dolor sit amet, consectetur adipiscing elit.'
 aaa.split("L").join("&")
//result: '&orem ipsum dolor sit amet, consectetur adipiscing elit.'

---

.join()

const elements = ['Fire', 'Air', 'Water'];

console.log(elements.join(' '));
// result: "Fire Air Water"

Others

function solution(phone) {
  console.log(phone.split("5678"))
  return phone.split(5678).join("****")
}

// split literally splits the string and puts them into array
// join is used in arrays
// then to that array, join ******

solution('01012345678')
