The Float64Array represents an array of 64-bit floating-point numbers in the platform byte order. By default, the contents of Float64Array are initialized with 0.
Float64Array.from() method is used to create a new Float64Array from an array-like or iterable object. So when you want to convert an arrayLike or iterable object to Float64Array then you can use this function by passing the object as a parameter to this function along with map function and value used for map function if needed.
Float64Array.from( source, mapFn, thisArg )
parameters: This method accept three parameters as mentioned above and described below:
- source: This parameter holds an array-like or iterable object which is used to convert into Float64Array object.
- mapFn: This parameter is optional which holds the Map function to call on every element of the Float64Array array.
- thisArg: This parameter is optional which holds the value to use as this when executing mapFn.
Return Value: This method returns a new Float64Array instance.
