Operators An operator performs some operation on single or multiple operands (data value) and produces a result. For example 1 + 2, where + sign is an operator and 1 is left operand and 2 is right operand. + operator adds two numeric values and produces a result which is 3 in this case.   Syntax: < Left operand > operator < right operand >   < Left operand > operator Example 1:  Arithmetic Operators Arithmetic operators are used to perform mathematical operations between numeric operands. Source code: var x = 10, y = 10 console.log("Addition Operator",x + y) console.log("Subtraction Operator",x - y) console.log("Multiplication Operator",x * y) console.log("Division Operator",x / y) console.log("Modulus Operator",x % y) console.log("Increment Operator",x ++ ) console.log("Decrement Operator",y -- )   Output: Addition Operator 20 Subtraction Operator 0 Mult...

Variables and Declarations What is Variable?

It is the service provided by the AWS as IAAS (Infrastructure as a Service). You can create/update resource on the cloud platform via cloud formation templates. Cloud formation template uses JSON or YAML language for scripting.  In simple words, this is the Infrastructure as code service by which you can provision a resource in the AWS cloud by writing the JSON or YAML code. Amazing right?   Advantages: ·         Code as a service – Since it’s a code based we can store the codes in Repository and maintain the version for the Infrastructure as well. ·         Provision of resource within short time ·         You...
