There was a time when Javascript was confined to the browser, much like Ebola was confined to a laboratory. The lab, like the browser, was a dangerous place. One could only enter after donning protective gear in the same way one must use JQuery. But those days are gone.

Ebola has escaped the lab. It's infected thousands of people in West Africa and literally billions of people in the United States. Likewise, Javascript has escaped the browser and runs on our servers and threatens our children.

It's too late to stop Ebola, but it's not too late to stop Javascript. All we need is a Javascript vaccine...

The software is checked very carefully in a bottom-up fashion. First, each new line of code is checked, then sections of code or modules with special functions are verified. The scope is increased step by step until the new changes are incorporated into a complete system and checked. This complete output is considered the final product, newly released. But completely independently there is an independent verification group, that takes an adversary attitude to the software development group, and tests and verifies the software as if it were a customer of the delivered product. There is additional verification in using the new programs in simulators, etc. A discovery of an error during verification testing is considered very serious, and its origin studied very carefully to avoid such mistakes in the future. Such unexpected errors have been found only about six times in all the programming and program changing (for new or altered payloads) that has been done. The principle that is followed is that all the verif
