How do I extract these info individually and store it in a variable where users can call it from a text file using node and javascript?

Answer 1

const fs = require('fs');
const path = require('path');

fs.readFile(path.join(__dirname, './text.txt'), { encoding: 'utf-8' }, (err, data) => {
  if (err) {
    console.log(err);
  }
  // split to lines, remove white space
  const result = data.split(/\n/g).map((line) => {
    return line.split(/\s+/).filter(Boolean);
  });
  console.log(result);

  // result content:
  // [
  //   ['Student', 'no.', '-', 'Class', 'no.'],
  //   ['123123', '-', '123123123'],
  //   ['Class', 'date:', 'abc', '123'],
  //   ['Year', 'number:', '123124'],
  //   [],
  //   ['Class', 'Period', 'period:'],
  // ];
});
