Reverse a string except for the characters contained within { } with javascript

I need to reverse a string except the characters inside of “{}”. I know how to reverse a string but I’m not sure how to create the exception. Please help.

 function reverseChar(string2){
    let string2Array = string2.split('');
    let newArray = [];
  
    for(let x = string2Array.length-1; x >= 0; x--){
      newArray.push(string2Array[x])
    }
    console.log(newArray)

}
reverseChar("ab{cd}efg")
reverseChar("ab{cd}ef{gh}i")

Answer

Or, maybe, this is what you want?

function reverse(str) {
  return str.split("").reverse().join("").replace(/}w+{/g,a=>reverse(a))
}

console.log(reverse("ab{cd}efg"))
console.log(reverse("ab{cd}ef{gh}i"))

The RegExp /}w+{/g will find any string of characters and numbers (w+) that is enclosed by } and {. These patterns will exist after the whole string is reverse()-d initially. In the callback function to the String.replace() method the matched string will then be reversed again.
