SDE1🏢 Zeta Practice Problem
Create a sampling function
Problem Description & Specifications
This question was asked in ZETA's SDE1 Frontend interview.
Create a function in JavaScript that accepts a function as input and a count and executes that input function once for a given count of calls. Known as sampling function.
function message(){
console.log("hello");
}
const sample = sampler(message, 4);
sample();
sample();
sample();
sample(); // this will be executed
sample();
sample();
sample();
sample(); // this will be executed
Note: You have to implement a function sampler that evaluates the above expression. There are no test cases to this. Test it yourself with different values.
