Comprehensive Guide to JavaScript String Methods
Character Access
The charAt() method retrieves the character at a specific index position. Modern JavaScript also supports bracket notation for the same purpose.
const text = 'developer';
console.log(text.charAt(0)); // 'd'
console.log(text[0]); // 'd' (equivalent)

Comprehensive Array and Object Array Deduplication in JavaScript
Basic Array Deduplication Using Set
For primitive-value arrays, Set provides an elegant and native solution:
const input = ['Zhang San', 'Zhang San', 'Three Zhang San'];
const uniqueSet = new Set(input);
console.log([...uniqueSet]); // ['Zhang San', 'Three Zhang San']
Object Array Deduplication via reduce()
For arrays of objects where uniquen ...
