Q 1. We have declared a function in two ways in the following code, one normal and the other with an arrow, which generates two alternative scenarios using "this" in the function. let data={
name:"jenifer",
getName:function()
{console.warn("normal",this)},
getNameArrow:()=>{
console.warn("arrow",this)}}
data.getName();
data.getNameArrow();

->Normal function is using parent "this"
    -> Arrow function has own "this", he is using both "this"
->Normal function is using child "this"
    -> Arrow function has own "this", he is using parent "this"
->Normal function is using own "this"
