Write a JavaScript program to initialize a two-dimensional array of given size and value. Use Array.from() and Array.prototype.map() to generate h rows where each is a new array of size w. Use Array.prototype.fill() to initialize all items with value val. ...
In this example,Arrays.deepEquals()is used to compare two simple one-dimensional arrays containing strings. Since the arrays contain the same elements in the same order, the method returnstrue.
