Unlike other variables, it is not affected by lexical scope. Compared to other languages, JavaScript behaves slightly differently when using the "this" keyword of a function. There are some further changes between strict and non-strict mode. The way the function is most commonly called determines the value of "this" (runtime binding). It may change each time the function is called, and cannot be changed by assignment at execution time. letter
