A self invoking function that can calculate compound interests
(function calc(){
// p is principal amount
let p=100000;
// t is time
let t=16;
// r is interest rate
let r=7.6
// x is the final interest
let x=p;
for(let i=1;i<t;i++){
if(i==1){
x*=(1+r/100);
}
x=(p+x)*(1+r/100);
}
console.log(x)
})()
