Basic JavaScript is a significant part of the aptitude test, covering fundamental concepts like variables, data types, control structures, functions, and objects. Here are some sample questions to help you prepare:

Sample Questions

Question: What is the result of the following JavaScript code?

        let a  5;
        let b  10;
        let c  (a > b) ? a : b;
        console.log(c);
    

Question: Which of the following is the correct way to define a function in JavaScript?

        // a) let sum  (a, b) { return a   b; }
        // b) let sum  (a, b)  return a   b;
        // c) let sum(a, b) { return a   b; }
        // d) let sum(a, b) { return a   b; }
    

Question: What will be the output of this code snippet?

        let arr  [1, 2, 3, 4, 5];
        for(let i  0; i  arr.length; i  ) {
            console.log(arr[i] * 2);
        }

Sample Questions

Question: You are given a table showing the sales of three products (A, B, C) for four consecutive years. Which product shows the highest growth rate from Year 1 to Year 4?

        | Year | A | B | C |
        |------|---|---|---|
        | Year 1 | 100 | 200 | 150 |
        | Year 2 | 150 | 250 | 200 |
        | Year 3 | 200 | 300 | 250 |
        | Year 4 | 250 | 350 | 300 |
    

Question: Below is a pie chart showing the market share of five different software companies. Which company has the smallest market share?

        #Given a pie chart with the following slices:
        | Company | Market Share |
        |---------|-------------|
        | X       | 20%         |
        | Y       | 30%         |
        | Z       | 25%         |
        | W       | 15%         |
        | V       | 10%         |
    

3. Algorithm Analysis and Time Complexity

Algorithm analysis and time complexity are essential topics tested in the Accion Lab aptitude test. This section ensures that you can evaluate the efficiency of algorithms and choose the optimal solution for specific problems. Here are some sample questions and explanations:

Sample Questions

Question: Analyze the time complexity of the following algorithm:

        for (let i  0; i  n; i  ) {
            for (let j  0; j  n; j  ) {
                console.log(i * j);
            }
        }
    

Question: Consider the following recursive function:

        function factorial(n) {
            if (n  0) {
                return 1;
            }
            return n * factorial(n - 1);
        }
    

Question: What is the time complexity of the following algorithm?

        function search(arr, target) {
            for (let i  0; i  arr.length; i  ) {
                if (arr[i]  target) {
                    return i;
                }
            }
            return -1;
        }
