how do i call a js method 3f

1function runFunction() {
2  myFunction();
3}
4
5function myFunction() {
6  alert("runFunction made me run");
7}
8
9runFunction();

1function myFunc(p1, p2, pN)
2{
3     // here "this" equals "myThis"
4}
5let myThis = {};
6
7// call myFunc using myThis as context.
8// pass params to function arguments.
9myFunc.call(myThis, "param1", "param2", "paramN");

1// let us see what exactly CALL, BIND method in JS
2
3/* NOTE : (CALL , APPLY executes immediately) and
4(BOUND - it returns bounded function that execute later)
5
6NOTE : call will take its additinal arguments just like that 
7	   eg : XYZ.call(this , a , b , c);
8       
9NOTE : apply will take its additinal arguments as an ARRAY
10       eg : XYZ.apply(this , [a , b , c])
11
12NOTE : All of them are for borrowing values(property and methods)
13	   from another function
14*/
15
16/*CALL method  {let's say we have constructor func}, we need all these
17properties and methods in another function, in that way CALL is 
18highly useful */
