Consider this: one-third of all recorded programming languages were developed in English-speaking countries (e.g., JavaScript), and many software engineers in other countries developed their programming language in English to make it more internationally marketable (e.g., PASCAL from Switzerland, Python from the Netherlands, Lua from Brazil).
Essentially, English is the universal trade language for coding, and even if a programming language is written in a different spoken language, most of its keywords will still be in English. This is because programmers need to communicate using a standard language of codes, which is currently English.
With this in mind, learning English for computer programmers could make or break your career.
