  • Functional programming concepts
  • Object-oriented programming in JavaScript

Here’s a simple example of modern JavaScript you might be expected to understand and write:

const fetchUserData = async (userId) => {
  try {
    const response = await fetch(`https://api.example.com/users/${userId}`);
    const userData = await response.json();
    return userData;
  } catch (error) {
    console.error('Error fetching user data:', error);
    return null;
  }
};

// Usage
fetchUserData(123).then(data => {
  if (data) {
    console.log('User data:', data);
  } else {
    console.log('Failed to fetch user data');
  }
});

2. Web Technologies

Common Coding Challenges

During your Figma interview, you may encounter coding challenges that test your problem-solving skills and coding ability. Here are some types of problems you might face:

1. String Manipulation

Given Figma’s text handling capabilities, string manipulation questions are common. For example:

// Problem: Implement a function that reverses words in a sentence
function reverseWords(sentence) {
  return sentence.split(' ').map(word => 
    word.split('').reverse().join('')
  ).join(' ');
}

console.log(reverseWords("Hello Figma")); // Output: "olleH amgiF"

2. Array Transformations

Figma deals with layers and objects, which are often represented as arrays. You might encounter questions like:

// Problem: Flatten a nested array
function flattenArray(arr) {
  return arr.reduce((flat, toFlatten) => 
    flat.concat(Array.isArray(toFlatten) ? flattenArray(toFlatten) : toFlatten), 
  []);
}

console.log(flattenArray([1, [2, [3, 4], 5]])); // Output: [1, 2, 3, 4, 5]

3. Tree Traversal

Understanding tree structures is crucial for working with Figma’s layer hierarchy. You might be asked to implement tree traversal algorithms:

class TreeNode {
  constructor(value) {
    this.value = value;
    this.left = null;
    this.right = null;
  }
}

function inorderTraversal(root) {
  const result = [];
  
  function traverse(node) {
    if (node) {
      traverse(node.left);
      result.push(node.value);
      traverse(node.right);
    }
  }
  
  traverse(root);
  return result;
}

// Usage
const root = new TreeNode(1);
root.left = new TreeNode(2);
root.right = new TreeNode(3);
root.left.left = new TreeNode(4);
root.left.right = new TreeNode(5);

console.log(inorderTraversal(root)); // Output: [4, 2, 5, 1, 3]

4. Implementing Design Patterns

You might be asked to implement or explain common design patterns. For instance, the Observer pattern is relevant to Figma’s real-time collaboration features:

class Subject {
  constructor() {
    this.observers = [];
  }

  addObserver(observer) {
    this.observers.push(observer);
  }

  removeObserver(observer) {
    const index = this.observers.indexOf(observer);
    if (index > -1) {
      this.observers.splice(index, 1);
    }
  }

  notifyObservers(data) {
    this.observers.forEach(observer => observer.update(data));
  }
}

class Observer {
  update(data) {
    console.log('Received update:', data);
  }
}

// Usage
const subject = new Subject();
const observer1 = new Observer();
const observer2 = new Observer();

subject.addObserver(observer1);
subject.addObserver(observer2);

subject.notifyObservers('New design change');
