Time is infinite, but a computer’s memory isn’t

In low-level coding, we usually have to specify the length of a variable. We have many types, including int32 and int64, which represent numbers in binary, using 32 bits or 64 bits, respectively. The int32, of number 4 for example, looks like this: 00000000 00000000 00000000 00000100 That’s it – 32 zeros or ones to... » read more

Origins of Javascript and Why We Prefer “Let” Instead of “Var”

In the 1930s, Alonzo Church introduced Lambda calculus. It is a formal system for expressing mathematical logic and computations using functions. Long before computations were performed by machines, they were done by humans, and Lambda calculus helped formalize these processes in written form. Lambda calculus looks like this: λx.x*2 // function that takes input xx... » read more
