Programming Language is the most important prerequisite for almost every discipline, whether it is Web Development, Machine Learning, Data Science, or any other. The total number of existing programming languages is estimated from 250 to about 700.
But of these hundreds of programming languages, CEOs of Apple, Facebook, Google and Microsoft founder used these programming languages. But remember, these languages may not be as relevant in today’s world as they were back then when all these tech companies were created.
Bill Gates
"I was 13 years old when I fell in love with programming," he wrote on his blog, Gates Notes, in 2018. "My friends and I would spend hours creating new programs and plugging away in BASIC," he said, adding that the introduction to computer science changed the course of his life.
Bill Gates was proficient at BASIC and assembly(most popular languages those days).
However, Microsoft developed C# as a replacement for Java, after they had a falling out with Sun over Java. So Microsoft uses C# where it would've made sense to use Java .
Tim Cook
Apple CEO Tim Cook always speaks passionately about the importance of teaching coding to children of all ages, and last week in an interview, he even said that if you have to make a choice, it's more important to learn to code than to learn a foreign language.
Being the CEO of Apple, Tim Cook naturally advocates the use of Swift and wants developers to use Swift to create new applications.
Sundar Pichai
Sundar Pichai was hired by Google not for his coding abilities, but for his excellence in product management. However, if you must know, Googlers are all about Python, Javascript, C++ and Java. GitHub’s recent State of the Octoverse report had Javascript, Python and Java as the top three programming languages, with C++ ranking 6th.
Mark Zuckerberg
When Mark Zuckerberg started work on Facebook in late 2003, he used a programming language called PHP. It was one of the most popular web languages of the day. Facebook now runs on Hack. Hack is a programming language for the HipHop Virtual Machine, created by Facebook as a dialect of PHP.
