Javascript array from() is an inbuilt function that creates a new, shallow-copied array instance from an array-like object or iterable object.
The Array .from() lets you develop Arrays from the array-like objects (objects with a length property and indexed items) or iterable objects ( objects where you can get its items, such as Map and Set).
The Array from() function was introduced in ECMAScript 2015.
Array.from() method in Javascript is used to creates a new array instance from a given array. If you pass a string to the Array.from() function, then, in that case, every alphabet of the string is converted to an element of the new array instance. In the case of integer values, a new array instance simply takes the elements of the given Array.
The syntax of the Array.from() method is the following.
Array.from(arrayLike[, mapFn[, thisArg]])
#javascript #ecmascript #javascript array from #array.prototype.from
