let me explain apply method
function circle(r,d) {
return r*d;
}
var circleMeta = [12,12];//r,d
circle.apply(null, circleMeta );
if we want to pass all array value to argument of function than apply is good to use.
above code return two array value multiplication
it make array to flat value and pass to function argument as order as it in array in JavaScript

apply() method is like call() method .
apply method call function with given array 's value as argument
funct.apply(null,argsArray)
argsArray ' s all value passed to funct as argument .
spread syntax is work like same . it spread the array 's value
funct.apply(null,argsArray)==funct(...argsArray);
so pass spread syntax as argument is equal to use apply method .
