How parse JSON array into Javascript and in which file? [duplicate]

I keep having an error message and the JSON file is an array, what is incorrect in the code below?

fetch("products.json")
  .then(response => response.json())
  .then(json => console.log(json));

let parsed;

try {
  parsed = JSON.parse(json);
  console.log('JSON array parsed successfully')
} catch (err) {
  console.log('ERROR..')
}

console.log(parsed)
