🍪Character Acces

You can access individual characters within a string using square bracket notation. For example:

const str = 'Hello World';
console.log(str[0]); // Outputs "H"
console.log(str[1]); // Outputs "e"

You can also use this notation to modify individual characters in a string. For example:

const str = 'Hello World';
str[0] = 'h';
console.log(str); // Outputs "hello World"

Keep in mind that this technique does not actually modify the original string. It just creates a new string with the modified character. To update the original string, you would need to reassign it to a new value.

let str = 'Hello World';
str = str.substring(0, 0) + 'h' + str.substring(1);
console.log(str); // Outputs "hello World"
