Sometimes, we want to convert an integer array to a string array in JavaScript.

In this article, we’ll look at how to convert an integer array to a string array in JavaScript.

Convert an Integer Array into a String Array in JavaScript

To convert an integer array to a string array in JavaScript, we can use the map method to do so.

For instance, we can write:

const arr = [1, 2, 3, 4, 5];
const strArr = arr.map(String)
console.log(strArr)

to create the arr number array.

Then we call map on arr with the String function as its callback.

The String function takes in the item we want to convert into a string and return the string version of the argument as a result.

Therefore strArr is:

["1", "2", "3", "4", "5"]

Conclusion

To convert an integer array to a string array in JavaScript, we can use the map method to do so.

Sometimes, we want to check if two JavaScript dates have the same date info.

In this article, we’ll look at how to check if two JavaScript dates have the same date info.

Check if Two JavaScript Dates Have the Same Date Info

To check if two JavaScript dates have the same date info, we can use the valueOf or getTime method to return the timestamp value of both dates, which are numbers.

Then we can compare the returned timestamp numbers with === .

For instance, we can write:

const a = new Date(1995, 11, 17);  
const b = new Date(1995, 11, 17);  
console.log(a.getTime() === b.getTime())

Then the console log logs true since a and b have the same timestamp number.

Also, we can use valueOf by writing:

const a = new Date(1995, 11, 17);  
const b = new Date(1995, 11, 17);  
console.log(a.valueOf() === b.valueOf())

And we get the same result as the previous example.

Conclusion

To check if two JavaScript dates have the same date info, we can use the valueOf or getTime method to return the timestamp value of both dates, which are numbers.

Then we can compare the returned timestamp numbers with === .
