JavaScript fundamental (ES6 Syntax): Exercise-33 with Solution
Write a JavaScript program to get a random number in the specified range.
- Use Math.random() to generate a random value, map it to the desired range using multiplication.
Sample Solution:
JavaScript Code:
//#Source https://bit.ly/2neWfJ2
const random_Number_In_Range = (min, max) => Math.random() * (max - min) + min;
console.log(random_Number_In_Range(2, 10));
console.log(random_Number_In_Range(1, 5));
console.log(random_Number_In_Range(-5, -2));
console.log(random_Number_In_Range(0, 1));
Sample Output:
5.897778190464821 1.1596294444724986 -2.644812110240778 0.5654096114937668

JavaScript: Tips of the Day
Chunks an array into n smaller arrays
Example:
const tips_chunkIntoN = (arr, n) => { const size = Math.ceil(arr.length / n); return Array.from({ length: n }, (v, i) => arr.slice(i * size, i * size + size) ); } console.log(tips_chunkIntoN([1, 2, 3, 4, 5, 6, 7,8], 4));
Output:
[[1,2],[3,4],[5,6],[7,8]]
