How to do Reverse a string in Javascript using recursion - Data Structures and Algorithms Interview Question for Frontend Interviews

[brokeloser]

It may be more optimized but higher JS payload size compared to the array approach.

[xtraszone]

Recursive functions is never considered as optimised approach

[gauravmasalkar]

We can convert string to array then reverse it and then again convert it into string like following

[sachintendulkar]

Using pointer and using while loop we can solve this right?
By swapping, which will reduce memory space as well

[SK_Covers]

Me: Simple for loop with string length, just decrease the count 😂😂😂

[kartikxisk]

What if string is null. It will throw error

[IllIIIIIIllll]

Sir are you using computer glass or a power glass?

[officialpage]

Good one but not optimised use one loop for this o(n)

[terminator]

So why does the code stope running when it reaches “Olleh” why doesn’t it just run forever I don’t understand

[venkatsai]

function Arr(val){
if(val===''){
return '';
}else{
return
}
}

console.log(Arr('hello'))

it showing maximum call stack size exceed

[venkateshp]

Bro it won't work...there is no possibility for str as empty string...how it is working at your side...

[armorkinggaming]

It's pointless to use all these methods. Readalibilty is poor.

Just run a for loop in reverse.

let newStr= ' ';
for (let i = str.length -1; i>=0;i--){
newStr += str[i];
}


return newStr;



Very simple way. Why trying all this?

[LeagueJeffreyG]

This is overcomplicating something very simple. Even if you had 10mil characters in one string and passed it into this function it would make such a minimal difference

[k.balamugundanbala]

Brother i have typed the same code but it gave the o/p like --> Maximum call stack size exceeded....why ????

[keeganfargher]

Don't ever write code like this. No company would accept this code in a pull request. It's very difficult to understand what it's doing
