Read MoreGet minimum number without a Math function JavaScript
We need to find the smallest number from a set of numbers without using JavaScript's built-in Math.min() function. This requires implementing our own comparison logic. Approach Using While Loop We'll iterate through all numbers and keep track of the smallest value found so far, updating it whenever we encounter a smaller number. Example const numbers = [12, 5, 7, 43, -32, -323, 5, 6, 7, 767, 23, 7]; const findMin = (...numbers) => { let min = Infinity, len = 0; while(len < numbers.length) { ...
Read MoreCreating a JavaScript Object from Single Array and Defining the Key Value?
JavaScript provides several ways to create objects from arrays and define key-value pairs. This is useful when transforming data structures or converting between different formats. Using Object.entries() with map() The most common approach uses Object.entries() to convert an object into an array of key-value pairs, then map() to transform the structure: var studentObject = { 101: "John", 102: "David", 103: "Bob" }; var studentDetails = Object.entries(studentObject).map(([studentId, studentName]) => ({ studentId, studentName })); console.log(studentDetails); ...
Read MoreTake two numbers m and n & return two numbers whose sum is n and product m in JavaScript
We need to write a JavaScript function that takes two numbers m (product) and n (sum) and returns two numbers whose sum equals n and product equals m. If no such numbers exist, the function should return false. This is essentially solving a quadratic equation where we need to find two numbers x and y such that x + y = n and x × y = m. Mathematical Approach We can solve this using the quadratic formula. If x + y = n and x × y = m, then x and y are roots of ...
