JavaScript best practices you must know

1.  Use === Instead of == JavaScript utilizes two different kinds of equality operators:  ===  |  !==  and  ==  |  !=  It is considered best practice to always use the former set when comparing. "If two operands are of the same type and value, then === produces true and !== produces false." - JavaScript: The Good Parts However, when working with  ==  and  != , you'll run into issues when working with different types. In these cases, they'll try to coerce the values, unsuccessfully. 2.  Eval = Bad For those unfamiliar, the "eval" function gives us access to JavaScript's compiler. Essentially, we can execute a string's result by passing it as a parameter of "eval". Not only will this decrease your script's performance substantially, but it also poses a huge security risk because it grants far too much power to the passed in text. Avoid it! 3.  Don't Use Short-Hand Technically, you can get away wi...

The future of Artificial Intelligence: 6 ways it will impact everyday life

Technology moves at breakneck speed, and we now have more power in our pockets than we had in our homes in the 1990s. Artificial intelligence (AI) has been a fascinating concept of science fiction for decades, but many researchers think we’re finally getting close to making AI a reality.  NPR notes that in the last few years, scientists have made breakthroughs in “machine learning,” using neural networks, which mimic the processes of real neurons. This is a type of “deep learning” that allows machines to process information for themselves on a very sophisticated level, allowing them to perform complex functions like facial recognition. Big data is speeding up the AI development process, and we may be seeing more integration of AI technology in our everyday lives relatively soon. While much of this technology is still fairly rudimentary at the moment, we can expect sophisticated AI to one day significantly impact our everyday lives. Here are 6 ways AI might affect us in the ...
