Node.JS Path Module and Some of its Methods

Various frameworks and platforms are available for developers to utilise to ensure the applications they create for the clients are smooth and fast. Node.js is a very popular framework among these developers. Node js is a runtime environment that is executed on the Chrome V8 engine. This library is known to execute JavaScript code out of the constraints of the web browser. It is an open-source, cross-platform, back-end environment that lets developers produce dynamic content for web pages. It uses an event-driven and non-blocking I/O model which makes it lightweight and efficient. It can also run on various platforms including Windows, Linux, Mac Os, etc. There are many inbuilt modules in Node.js that make it popular and the Node.js path is one of them. 

What is the Path module?

There are many modules that Node provides but the path module is one of the more useful ones that is often forgotten or ignored. This module has many methods and the primary function for most of these is to easily interact with and manipulate file paths by helping developers with pathnames of files and directories on the system. 

Some Path methods and their uses

  • Path.join()-

In Node.js Path, join() is the most commonly used method by developers. It is used to join various parts of a file path into a string. If the application needs this file path anywhere else, this string can be used. Apart from joining many path segments, it does so by using as a delimiter, a separator that is specific to the platform. Delimiters for different operating systems like windows and MAC are different. With a platform-specific separator, the program doesn’t break when the path is explicitly stated on different OSs. It also normalises the resulting path and returns it. It returns a string and if the string of the joined path is zero-length, ‘.’ is returned. 

  • path.basename()-

Another commonly used method, invoking it will return the directory referring to the file or the name of the file or returns the later portion of any specific path, much like the Unix command of the same name. This function treats these names in a case-sensitive manner even though Windows does not. Extensions like HTML are included in this method but developers can remove them through path.basename as well. 

  • Path.isAbsolute()-

An extremely useful method in Node.js Path, it is used to check if any specified path in the argument is an absolute path. An absolute path is when it contains all the necessary details required to locate any file. A string path is passed as an argument and a boolean (true or false) is returned. When the path is a zero-length string, the return is false. 

  • Path.delimiter()-

Another in-built programming interface, this method is used to find the delimiter according to the platform. The return comes in the form of a string that provides the platform-specific delimiter required. The return for windows is “;” and for POSIX is “:” 

Many such methods are available and are useful to developers.

Global Crypto Market Cap Threatens to Break Below Current 2022 Lows

mm

Published

on

The global cryptocurrency market capitalization topped during the first half of November 2021, and since then it has been on a one-way ride towards the downside. With the entire market currently trading at approximately 35% below all-time highs, many traders are now wondering whether the sellers are already exhausted, meaning that an upward shift is due in the near future, or whether the bear market still has room to go. 

In such a challenging environment, trading or investing in crypto is tricky, making it difficult for traders/investors to time the market correctly, and spot key support/resistance areas on the chart. All of the variables that drove valuations higher between 2020-2021 (fiscal/monetary stimulus, weaker fiat currencies, and appetite for riskier assets) have reversed, leaving bulls stumbling for the exit. 

Bitcoin weakens below $40k 

Speaking of Bitcoin, the $38,000 area is regarded as key support, which might be one of the reasons why the price is still trading around it. The late-March 2022 rally failed to gather pace and now BTC finds itself trading close to the yearly lows. 

Things are not looking encouraging, not just because Bitcoin lost 40% from its peak, but also based on the market share. During broad crypto selling, the BTC market dominance increased in past cycles. It doesn’t seem to be the case now, as the figure has stabilized around 42% since mid-2021. Investors want to keep a diversified exposure even during a downturn, and this is a clear signal that Bitcoin’s safe-haven status is weakening. 

Major altcoins not showing signs of strength

Anyone who is just beginning to learn how to trade cryptocurrencies should know that this is an environment where caution is advised. Bitcoin aside, things are not looking very good for the altcoins sector as well. Based on the opening price at the beginning of 2022, Ethereum is down 24%, Binance Coin -26% and other tokens such as Solana are posting losses above 50%. 

There this might not be the time for buy and hold, considering that valuations might be even more attractive in the future. It is possible, however, to take advantage of what retail brokerages are offering in terms of crypto trading benefits. With derivatives based on cryptocurrencies, short-selling is a viable option, making it possible to take advantage of bearish conditions. 

Inflation and broad risk appetite

Rising inflation around the world set a chain of events in motion, and these events are clearly not in favor of crypto bulls. Central banks are forced to step in and normalize monetary policies in developed countries, for price increases to diminish towards their target of around 2%. 

Additionally, fiscal spending is taking a few steps back, as governments need to pay higher interest on new debt or refinancing operations. During a time of rising prices, private and institutional investors need to make concessions and prioritize spending. 

In such an environment, the interest in volatile assets such as crypto is very low, which explains the lack of momentum. For the time being, global capitalization is trading around $1.72 trillion and threatens to break below the 2022 low of $1.64 trillion. Until the global economy receives a new round of stimulus, there appears to be little hope for a strong bounce back to a bull run.
