Sometimes, we want to fix geocoding from address to latitude and longitude numbers not working with JavaScript.

In this article, we’ll look at how to fix geocoding from address to latitude and longitude numbers not working with JavaScript.

How to fix geocoding from address to latitude and longitude numbers not working with JavaScript?

To fix geocoding from address to latitude and longitude numbers not working with JavaScript, we use the Google Maps API.

For instance, we write

<script
  type="text/javascript"
  src="http://maps.google.com/maps/api/js?sensor=false"
></script>

to add the Google Maps API script.

Then we write

const geocoder = new google.maps.Geocoder();
const address = "new york";

geocoder.geocode({ address }, (results, status) => {
  if (status === google.maps.GeocoderStatus.OK) {
    const latitude = results[0].geometry.location.lat();
    const longitude = results[0].geometry.location.lng();
    console.log(latitude);
  }
});

to call geocode with the address to geocode the address and get the resulting latitude and longitude with lat and lng respectively.

Conclusion

To fix geocoding from address to latitude and longitude numbers not working with JavaScript, we use the Google Maps API.

Sometimes, we want to get the difference between two dates in years, months, days in JavaScript.

In this article, we’ll look at how to get the difference between two dates in years, months, days in JavaScript.

How to get the difference between two dates in years, months, days in JavaScript?

To get the difference between two dates in years, months, days in JavaScript, we use the preciseDiff method.

For instance, we write

const starts = moment("2022-02-03 12:53:12");
const ends = moment();
const duration = moment.duration(ends.diff(starts));
const diff = moment.preciseDiff(starts, ends, true);
const diffHuman = moment.preciseDiff(starts, ends);

to get the duration between the starts and ends date with moment.duration and diff.

And then we call precisediff to get theg precise difference between the 2 dates.

Conclusion

To get the difference between two dates in years, months, days in JavaScript, we use the preciseDiff method.

Sometimes, we want to use JavaScript switch with logical operators.

In this article, we’ll look at how to use JavaScript switch with logical operators.

How to use JavaScript switch with logical operators?

To use JavaScript switch with logical operators, we use true as the expression to compare.

For instance, we write

switch (true) {
  case count >= 4:
    console.log("lol");
    break;
  case count > 3:
    console.log("bye");
    break;
  case count == 2:
    console.log("hi");
    break;
}

to use true in the parentheses and then we can use any boolean expression we want for the case statements.

Conclusion

To use JavaScript switch with logical operators, we use true as the expression to compare.

import { useHistory } from "react-router-dom";

to import the useHistory hook.

Then we write

const history = useHistory();

to get the history object from the hook.

Then we use

history.push("/foo");

in a component function to navigate to /foo.

Conclusion

To fix Uncaught TypeError: Cannot read property ‘push’ of undefined with React-Router-Dom, we call the useHistory hook.
