When utilizing C Language, int myArray[42] = { 0 }; is a method that initializes all values in the array to 0 from the beginning. Is there a comparable approach available for use in TypeScript?

If you want to fill all elements of an array with a specific value, you can utilize the Array.prototype.fill() method.
The fill() method is used to set all elements in an array from a specified starting index to an ending index with a predetermined static value.
let arr = new Array(30);
arr.fill(0); // Replace all elements in the array with 0
When working with C Language, initializing all values in an array to 0 can be done by declaring int myArray[42] = { 0 }; at the beginning. Is there a similar method available in typescript?
If you are using JavaScript's latest version, you can achieve this using Array.from:
Array.from({length:10}); // Array of `undefined x 10`
Additionally, it is possible to assign a different value like so:
Array.from({length:10}).map(x=>0); // Array of `0 x 10`
