I have these lines of code to transform an array

const regex = new RegExp(req.params.keyword, 'i');
const fields = ['fname', 'lname'];
const arrayOfRegex = [];
// eslint-disable-next-line no-restricted-syntax
for (const f of fields) {
  arrayOfRegex.push({ f: regex });
}
console.log(arrayOfRegex);

My expected output is

[{ fname: /pyt/i }, { lname: /pyt/i }]

But I got this what went wrong?

[ { f: /pyt/i }, { f: /pyt/i } ]
