What\'s the Most Efficient Way to Create Zero-Filled Arrays in JavaScript?

Creating Zero-Filled JavaScript Arrays Efficiently

Creating zero-filled arrays of arbitrary lengths in JavaScript can be achieved through various approaches. Among them, the most efficient method introduced in ES6 is utilizing the Array.prototype.fill method.

Using Array.prototype.fill:

new Array(len).fill(0);

This approach generates a new array of the specified length and fills it with the provided value (in this case, zero). It offers a concise and self-explanatory solution.

Compatibility and Performance

While Array.prototype.fill is fast and efficient in modern browsers, it may not be supported in older browsers such as IE. To address this, a polyfill can be employed to extend compatibility. While there are alternative techniques available, the fill method has emerged as the most efficient solution for creating zero-filled JavaScript arrays.
