If you optimize your JavaScript code with these hacks, it can help you write cleaner code, save resources, and optimize your programming time. According to RedMonk, JavaScript is the most popular programming language. Furthermore, SlashData estimates that around 12.4 million developers use JavaScript, which also includes CoffeeScript and Microsoft’s TypeScript. This means that millions of people use JavaScript to work as programmers, take freelance gigs through sites like UpWork and Freelancer, or even start their own web developing businesses. freeCodeCamp has an excellent basics course on JavaScript. But, if you’re already familiar with the fundamentals and want to advance your proficiency in JavaScript, then here are ten hacks you should learn and integrate into your workflow. 1. How to Use Shortcuts for Conditionals JavaScript allows you to use certain shortcuts to make your code easier on the eyes. In some simple cases you can use logical operators && and || instead of if and else. Let’s look at the && operator in action. Example snippet: The || operator functions as an “or” clause. Now, using this operator is a bit trickier since it can prevent the application from executing. However, we can add a condition to get around it. Example snippet: 2. How to Convert to an Integral Using the ~~ Operator Removing decimals to return an integral using math.floor or math.round takes up resources. A more efficient way is using the ~~ operator. Example snippet: 3. Resize or Empty an Array Using array.length Sometimes you need to adjust the size of your array or empty it. The most efficient way to do this is using array.length. Example snippet:...
A guide to government financial assistance for small businesses. Over the past year, lockdowns and restrictions have rapidly brought forward timelines on plans to digitise business for many organisations. New technologies across industries have been implemented to allow companies to remain in business as well as connected to colleagues and clients from anywhere. The uptake and use of cloud-based technology, e-commerce platforms, and new digital technologies is expanding, and the Singapore government has stepped in to support small to medium sized businesses in going digital. SMEs are an essential foundation of the Singapore economy, employing two thirds of the workforce and contributing nearly half of Singapore’s GDP. While the uptake and roll-out of digital tools started as a necessity to enable businesses to continue operating, there has been a growing acceptance and appreciation for the benefits of a digitised workplace. The Singapore IMDA launched the SMEs Go Digital programme, promoting the use and update of digital technologies to build stronger digital capabilities. These alongside other existing government grants can make a huge difference to businesses who have been hard hit over the past year. Productivity Solutions Grant The Productivity Solutions Grant (PSG) supports businesses in the adoption of IT solutions or equipment that improves business productivity. The PSG grant supports sector-specific solutions as well as solutions which benefit all industries. Solutions are pre-scoped by government agencies, including Enterprise Singapore, the National Environmental Agency (NEA) and the Singapore Tourism Board (STM). How much is the Productivity Solutions Grant? In 2020, PSG was enhanced to encourage the digitisation of small business, to counter the effects of restrictions due to COVID-19. As...
1 TL;DR Cheatsheet For those of you in a hurry, the following chart is a “too long; didn’t read” summary. 1 Framework Comparison DISCLAIMER: The following comparisons are subjective. What would be counted as a strength in one case could be considered a drawback in another. For example, using complex CSS3 selectors in jQuery lets you do a lot with a single line of code, but that does not mean it is the most efficient way to interact with the Document Object Model. 1.1 The jQuery Library The jQuery library is a modular set of cross-browser methods for making AJAX requests, manipulating elements, triggering and listening for events, selecting elements from the DOM, running animations and effects, getting and setting form input values, traversing the DOM, using deferred promises to manage future events, and more. It works as a facade to standardize and ease the task of programmatically interacting with elements on a web page. 1.1.1 Intuitive API Even as modern browsers are becoming more standardized, there is no doubt that cross-browser DOM manipulation is still painful. One of the greatest strengths of the jQuery library is its clean and intuitive API. New developers have no trouble picking it up quickly, yet it is powerful enough for JavaScript experts to leverage as well. Suppose we have the following HTML markup, and we want to add the text ‘World’ to the message ‘Hello’ when the button is clicked the first time. The following Vanilla JavaScript code demonstrates one way to do this (live example). In contrast, it is trivial to do the exact same thing with jQuery (live example). Pretty...
Considering the ongoing efforts to improve the world’s ecosystem and climate conditions, more countries are investing in smart technologies and micromobility. This led to a boost in the bike-sharing industry where companies managed to get good amounts of funding from many investors.

In Southern California, one hardworking mom isn’t just looking out for her own children in our increasingly dangerous world—she’s helping to rescue countless others. In an eye-opening interview with The Epoch Times, Santa Ana mom Kerry Torres described her crucial work as a Police Investigative Specialist, combing the web for traces of child exploitation and sexual abuse materials under the Santa Ana Police Department (SAPD). Torres spends her days seeing the absolute worst of the internet—and helping to fight it—and comes home to her own children. “To come home and to be a mom, and not bring it home and not let it affect me, that’s always a challenge,” Torres told The Epoch Times. “Because sometimes I don’t want to turn off my computer, sometimes I don’t want it to be end of day—because there’s one thing more I could be doing.” Since SAPD created its online task force last year, Torres has closed about 180 cases of child exploitation. “There’s probably nothing worse than what investigators have to watch and what we look at,” she said. “The whole job is a challenge—to be able to do what I do, and give my 100 percent focus to my victims that are out there and that need help.” Torres and the department’s task force cooperate with the Internet Crimes Against Children Task Force (ICAC), a collaboration of 61 federal, state, and local agencies and more than 4,500 officials investigating online crimes against children. Most of the tips assigned to Torres come from The National Center for Missing and Exploited Children (NCMEC), a tip line and data reporting service for exploited...
