Question

Define a JavaScript function named thanos which has a single parameter. This function will be called so that the parameter will be an array. Your function should return a NEW array which contains only the entries at even indices. (Hint: you can tell an index is even if that index mod 2 is equivalent to 0).. Examples: thanos([ ]) would evaluate to [ ] thanos(['0', 2, 4]) would evaluate to ['0', 4]

Answer 1

Answer:

See explaination

Explanation:

function thanos(lst) {

var result = [];

for (var i = 0; i < lst.length; i += 2) {

result.push(lst[i]);

}

return result;

}

// Testing the function here. ignore/remove the code below if not required

console.log(thanos([]));

console.log(thanos(['0', 2, 4]));
