JS: Iterate String

Enumerate Chars in String via For-Of Loop

Best way to go thru each char in string is using for-of Loop.

for (let x of "a😃c") { console.log(x); }

// a
// 😃
// c

Convert String to Array

Another way is to convert string to array, then use any array methods to go thru.

[..."a😃c"].forEach( ((x) => { console.log(x); }) );

// prints
// a
// 😃
// c

• Spread Operator
• Array.prototype.map
• Array.prototype.forEach

Using For-Loop (go thru 16-bits units)

If string contains emoji or rare Unicode character, for-loop behaves in unexpected way. (for why, see 〔see JS: String Code Unit〕 )

const str = "a😃c";

for (let i = 0; i < str.length; i++) {
  console.log(str[i]);
}

// prints
// a
// �
// �
// c
