Assignment Operators And Comparision Operators In Java Script | Complete Java Script Course| #5

In this Video We have share the Knowledge of Assignment Oprators And Comparision Operators which is used in Java Script.


The assignment operator = assigns the value of its right-hand operand to a variable, a property, or an indexer element given by its left-hand operand. The result of an assignment expression is the value assigned to the left-hand operand. The type of the right-hand operand must be the same as the type of the left-hand operand or implicitly convertible to it.

This chapter describes JavaScript's expressions and operators, including assignment, comparison, arithmetic, bitwise, logical, string, ternary and more.

At a high level, an expression is a valid unit of code that resolves to a value. There are two types of expressions: those that have side effects (such as assigning values) and those that purely evaluate.

The expression x = 7 is an example of the first type. This expression uses the = operator to assign the value seven to the variable x. The expression itself evaluates to 7.

The expression 3 + 4 is an example of the second type. This expression uses the + operator to add 3 and 4 together and produces a value, 7. However, if it's not eventually part of a bigger construct (for example, a variable declaration like const z = 3 + 4), its result will be immediately discarded — this is usually a programmer mistake because the evaluation doesn't produce any effects.

As the examples above also illustrate, all complex expressions are joined by operators, such as = and +. In this section, we will introduce the following operators:

Assignment operators
Comparison operators
Arithmetic operators
Bitwise operators
Logical operators
BigInt operators
String operators
Conditional (ternary) operator
Comma operator
Unary operators
Relational operators
These operators join operands either formed by higher-precedence operators or one of the basic expressions. A complete and detailed list of operators and expressions is also available in the reference.
