JavaScript Functions and prototype1. Defining a function can be declared or an expression.(1) function declaration:A semicolon is used to separate executable JavaScript statements. function declaration is not an executable statement, so it does not end with a semicolon.
function a(){ console.log('bbb');}(2) function expression:
The function expression ends with a semicolon because it is an execution statement.
var a = function(){ console.log('aaa')
