A global variable has global scope which means it can be defined anywhere in your JavaScript code. To minimize the usage of global variables, use consistent variables around different parts of your project.var myValue = {    common: function(){       //Add code    },    val1: {       myVar1: "Demo String One",       func1: function(){          //Add some code       },    }    val2: {       myVar1: "Demo String Two",       func1: function(){          //Add another code       },    }    val3: {       myVar1: "Demo String Three",       func1: function(){          //Add another code here       }    } };

Avoid global variables or minimize the usage of global variables in JavaScript. This is because global variables are easily overwritten by other scripts. Global Variables are not bad and not even a security concern, but it shouldn’t overwrite values of another variable.On the usage of more global variables in our code, it may lead to a maintenance issue. Let’s say we added a variable with the same name. In that case, get ready for some serious bugs.To avoid the usage of global variables, use the local variables and wrap your code in closures. You can also avoid this by wrapping ... Read More

Commonly, adding semicolons in JavaScript is optional. Simple statements in JavaScript are generally followed by a semicolon character, just as they are in C, C++, and Java. JavaScript, however, allows you to omit this semicolon if each of your statements is placed on a separate line.No need of a semicolon in a function declaration:function functionname(s) { }If the function is written as a statement, it should have a semicolon like any other statement in JavaScript:var a = function functionname(s) { };
