Variables, DataTypes, Operators and Expressions
Global variables (Global Scope)
Local and Block level variables (Local Scope)
Let’s look at some code.
Numbers : eg: 157, 457
Strings : eg: “This is string”, ‘This is string’
Booleans : eg: true or false
For ex: If we assign 124 value to a variable var myValue = 124. The data type for myValue will be Number.
Let’s look at some code and find out the data type of a variable (using the typeof keyword).
Operators allows us to compute data in a programming language.
In order for an operator to work it needs two operands.
4 + 5 = 9 Here, 4 and 5 are the two operands and + is the operator.
The Assignment assigns values from the right side operand to the left side operand.
+= (Add & Assignment) : adds the right operand to the left operand and assigns the result to the left operand.
-= (Subtract & Assignment) : subtract the right operand to the left operand and assigns the result to the left operand.
*= (Multiple & Assignment) : Multiples the right operand to the left operand and assigns the result to the left operand.
/= (Division & Assignment) : Divides the right operand to the left operand and assigns the result to the left operand.
%= (Modulus & Assignment) : Modulus operation happens from right operand to left operand and assigns the result to the left operand.
The Ternary operator first checks the expressions for a true or false value and then executes the given statements.
