Can we assign function to variable in JavaScript?

It is possible to use a function expression and assign it to a regular variable, e.g. const factorial = function(n) {…} . But the function declaration function factorial(n) is compact (no need for const and = ). It allows using the function before the declaration in the same scope.

How do you put a function into a variable?

we put the function in a variable if inside the function block we use the return method: var multiplyTwo = function (a) { return a * 2; }; if we simply call this function, nothing will be printed, although nothing is wrong with the writing of the function itself.

Can you assign a function to a variable in C #?

What does assignment mean in a programming language?

Assignment means: “storing a value (of a particular type) under a variable name”. Think of each assignment as copying the value of the righthand side of the expression into a “bucket” associated with the left hand side name!
