JavaScript: Create a n-dimensional array with given value
JavaScript fundamental (ES6 Syntax): Exercise-212 with Solution
Write a JavaScript program to create a n-dimensional array with a given value.
- Use recursion.
- Use Array.from(), Array.prototype.map() to generate rows where each is a new array initialized using initializeNDArray().
Sample Solution:
JavaScript Code:
//#Source https://bit.ly/2neWfJ2
const initializeNDArray = (val, ...args) =>
args.length === 0
? val
: Array.from({ length: args[0] }).map(() => initializeNDArray(val, ...args.slice(1)));
console.log(initializeNDArray(1, 3));
console.log(initializeNDArray(5, 2, 2, 2));
Sample Output:
[1,1,1] [[[5,5],[5,5]],[[5,5],[5,5]]]

JavaScript: Tips of the Day
Calculates the greatest common divisor between two or more numbers/arrays
Example:
const tips_gcd = (...arr) => { const gcd = (x, y) => (!y ? x : tips_gcd(y, x % y)); return [...arr].reduce((p, q) => gcd(p, q)); }; console.log(tips_gcd(5, 25)); console.log(tips_gcd(...[8, 16, 32]));
