First, create an empty array named eligible. Then loop through every astronaut in the input crew array and, if they are EVA-eligible (meaning their isEVAEligible property is true), push them into the eligible array. After the loop, return the eligible array.

--hints--

You should create an array named eligible.

const funcStr = __helpers.removeJSComments(getEVAReadyCrew.toString());
assert.match(
  funcStr,
  /(var|let|const)\s+eligible/,
  "You must have at least one space between the declaration keyword (let/const) and 'eligible'"
);
const cleaned = __helpers.removeWhiteSpace(__helpers.removeJSComments(getEVAReadyCrew.toString()));
assert.match(cleaned, /(?:^|[^a-zA-Z])(var|let|const)eligible=\[\]/);

You should use a for loop to iterate through the input crew array.

const cleaned = __helpers.removeWhiteSpace(__helpers.removeJSComments(getEVAReadyCrew.toString()));
assert.match(cleaned, /for\s*\(/);

You should return the eligible array.

const cleaned = __helpers.removeWhiteSpace(__helpers.removeJSComments(getEVAReadyCrew.toString()));
assert.match(cleaned, /returneligible;?}$/);

const sample2 = [{ isEVAEligible: true }];
assert.isArray(getEVAReadyCrew(sample2));

After calling getEVAReadyCrew(), the returned array should contain only EVA-eligible astronauts from the input array crew.

const sample = [
  { name: "A", isEVAEligible: true },
  { name: "B", isEVAEligible: false },
  { name: "C", isEVAEligible: true }
];
const result = getEVAReadyCrew(sample);
assert.deepEqual(result.map(a => a.name), ["A", "C"]);
