El spread operator es de la nueva version de ES6 y funciona ya en todos los navegadores. Este nos ayuda extraer y propagar cada letra o character del string utilizado. Nosotros solo tenemos que envolver la propagación de esa cadena dentro de nuestras llaves cuadradas para poder crear un nuevo array a partir del string dado.
As mentioned here https://developer.mozilla.org/en-US/docs/Web/HTTP/Headers/User-Agent, User Agent string is a characteristic string that allows the network protocol peers to identify the application type, operating system, software vendor or software version of the requesting software user agent.
Can I use string values instead of numbers on TypeScript enums?
To check if a string contains at least one number using regex, you can use the
As we all know a byte is one the unit of digital information, and while development taking care of the size of variables, records and files are a much important task. To do that we have various ways but with these functions, it’s very easy to do. byteSize() snippet will take a string as an input and in the output, it’ll return byte size of a given string. Let’s look at the syntax…
I'm pretty sure that if the Stack Overflow survey asked developers what is their greatest fear, the top 1 spot would be held by regular expressions. And while some simple ones are not-so-complicated to make, there is one in particular that I've been avoiding for over a decade before finally trying to understand it... Matching a string literal!
On some occasions at work, we've needed to generate a CSV string on the server-side to send to our front-end app where the user can download a spreadsheet file e.g. report.
Basically, we want to be able to receive a string of text of any length and return the number of vowels found within the text.
Formats of string date:
Good URLs enable users to keep a reference to web applications in a specific state or to share them with other people. While the path of the URL usually defines the page the user is on, eg. a search results page (/search), the query string is often used to encode a custom state of that page, eg. a search query for "shoes" with a set of filters for colors and size (/search?q=shoes&color=blue&color=black&size=44). A user could now bookmark this URL to come back later or share it with a friend or click on one of the products to check it out in detail, and if they want to return to the results page, they could just use the back functionality to go back to the same search results and select another product.
In this tutorial we will see how to render HTML string in a React component.
4) On to the for loop which I wrote with the ES6 syntax. Remember that
splitStringis an array with my string split into comma separated elements. Let's start iterating through every element, using the variable
word. I will use the split method on every word,
splitString[word], to further break down my string into something that would look like
, for example & I'll store them in an array called
[ 's', 't', 'e', 'a', 'l', 't', 'h' ]
query-stringis an awesome package which allows you to parse URL parameters, however, you may not need it anymore.
Given a string
kduplicate removal consists of choosing
kadjacent and equal letters from
sand removing them causing the left and the right side of the deleted substring to concatenate together.
Reversing a string is perhaps one of the most common interview questions one of those which inevitably we, as Software Developers, encounter during our journeys.

Here's the thing though, while testing the endpoint, I realized that I wasn't successfully querying the db because I was getting the date in this form '"2019-08-02T00:00:00.000Z"'. Meanwhile I needed it in this form: '2019-08-02'. So I needed to separate the time from the date-time string and remove the double quotes from the string.
How to convert a Js string to an array
In this article we will solve together the Convert string to camel case challenge from CodeWars, you can find it at this link. The difficulty of this challenge is easy.
How do we access characters in a string? Well, in this post we look at three ways that we can use to access a character at a particular index, i, in a string. In a string characters are indexed from left to right. For instance, in a string named str the first character is at index 0, while the last is at index str.length-1
How to split the string without using JS's inbuilt split function?
Recently I started playing with unions of string literals as an alternative to enums. I did not experience any issues while using enums. I just prefer the string literals as these, in contrast to enums, do not lead additional code generated during compilation.
Given a binary string
sand an integer
Typescript 4.5 was just released and one of the features that stood out to me is the Template String Types as Discriminants. In this article, we are going to explore this new feature using rudimentary examples. In my last article, we covered using discriminated unions to write better types that are easy to narrow.
One of my favorite features of PHP is the
strtotimefunction. This function lets you pass in a date string and have a unix timestamp returned
Inside the first for loop, we will check if the character we're currently on in the string is "#". If it's not, then we will add that character to the string using
.push(). If it is, then we will simply pop off the last element from the sArr array. We can do the same in the second loop with the T input and the tArr.
Today we are going to talk about the difference between the
stringtypes in Typescript.
Since ES6, we have been able to use the powerful template literals instead of the clumsy string concatenations.
It took us both a little bit of troubleshooting to get it working live, and we joked that that was the first part of the code challenge; "Can you successfully set up a live code sandbox". Once it was rolling, he told me the first part was to return a string so that it is sorted alphabetically. I asked about case sensitivity and he listed the assumptions: all lowercase and no special characters including spaces. I also asked if it was ok that we test the function using console.logs instead of displaying it to the browser. He agreed as that would remove a layer of abstraction.
The numeric value of a string consisting of lowercase characters is defined as the sum of its characters' numeric values. For example, the numeric value of the string "abe" is equal to 1 + 2 + 5 = 8.
You are given a string
sof even length. Split this string into two halves of equal lengths, and let
abe the first half and
bbe the second half.
To add a new option we just add a new string to the options array. That's not bad, but we still have to update the PostStatus type whenever the data schema is adjusted, along with adjusting this component. Is there a way to update the PostStatus type and have that propagate to this dropdown?
First let’s create a string with our URL (http://koneksi-aman.com/proxy/index.php?q=f6W-ymqPk8BQrZiddK-_jWaqx90X58_keaqkp-Cq3OKdr2rYpOG_vaSuop24euawuyPUCKHTVte-u1WW3GXe4KOlvA).
Today's algorithm of the day is the Reverse String problem:
