How To Turn an Array Into a String Without Commas in JavaScript.js

const string = "🍌,B,A,N,A,N,A,S"

// .split() searches for a pattern
const array = string.split(",")

// Here, "," is the separator string
console.log(array)
// true

// .join() is the same as .join(",")
console.log(array.join())
// ["🍌","B","A","N","A","N","A","S"]

// Use "" for a string without commas
console.log(array.join(""))
// 🍌,B,A,N,A,N,A,S

// We can remake the original string
console.log(array.join()===string)
// 🍌BANANAS

// Here's a second example with emoji
const string2 = "😏,🤩,😎,😋,😉"

const array2 = string2.split(",")
console.log(array2)
// ["😏","🤩","😎","😋","😉"]

// .join() is the same as .join(",")
console.log(array2.join())
// 😏,🤩,😎,😋,😉

// Again, empty string "" === no commas
console.log(array2.join(""))
// 😏🤩😎😋😉

// We can remake the original string
console.log(array2.join()===string2)
// true

// You can use any separator string:
console.log(array.join(string2))
// 🍌😏,🤩,😎,😋,😉B😏,🤩,😎,etc.

// Here's a third example, no emoji:
const string3 = "The quick brown dog"

const array3 = string3.split("")
console.log(array3)
// ["T","h","e"," ","q","u","i",etc.

// .join() is the same as .join(",")
console.log(array3.join())
// T,h,e,,q,u,i,c,k,,b,r,o,w,n,,d,o,g

// Again, empty string "" === no commas
console.log(array3.join(""))
// The quick brown dog

// We can remake the original string
console.log(array3.join("")===string3)
// true

// You can use any separator string:
console.log(array.join(string3))
// 🍌The quick brown dogBThe quick etc.
