The basics | Inbuilt Function of Js

How to declare a String in JS

Accessing Characters

Accessing Characters

Looping a string

Modifying Strings

Concat & Trim (Trim has only removed side spaces | didn't remove space in between )

Searching in String

Took a part from a string ( Slice, Subdtring)

Convert Case ( Str -> number | Num -> Str | etc..)

This is important because if we Typecast an Object in Js it gives a [ Object Object ] simple mines gives us its type

The Right way to do that

Convert a String

Check Ascii value or Convert to Ascii Value

String Compare

it returns 0 if it is the same otherwise -1

To check whether something is included in String or not

It returns True | False values

Splitting and Joining Strings

It breaks the string from " " (space) occurs

Finally The Main Data Structure & Algorithm Questions Start.

My Solution:

`const mainString = ' Hay Good Morning Brother';
const maxLenght = 10;

if (mainString.length >= maxLenght) {
let trimedvalue = mainString.trim();
let finalVersionOfString = trimedvalue.replaceAll(" ", "");
console.log(${finalVersionOfString.slice(0, 10)}...);
} else {
console.log(mainString);
}
// Output : HayGoodMor...`

Q2: Plaindrome:

My Solution:

I add comments with ChatGPT (I think it is a better approach because sometimes interviewers don't allow to use inbuilt functions of a language )

quick Question

Can Someone Explain?
Hey, I tried my best and approached this question in five different ways using JavaScript. The average runtime is around 140ms. However, when I attempted the same question in Java, it only took around 9ms. How is this possible? Why is there such a significant difference? Could someone please explain?

Question 03: 461. Hamming Distance

A quick tip: Convert a number to binary just | let num = 10; num.toString(2) --> that 2 refers base^2
I don't know why on leetcode in this program time limit exceeds.
