Arithmetic and Relational Operator in typescript

This tutorial explains Arithmetic and Relational Operator in typescript with examples.

Typescript arithmetic operator

Arithmetic operators are used in expressions with two or more entries.

This operator will work on numeric values.

These operators are very easy to understand as these are available in our study curriculums as well as other programming languages.

This evaluates Arithmetic operators on two operands.

Here is a syntax

operand1 operator operand2

Assume that p has a value of 20, and q has a value of 30.

Operator	Title	Description	Example
`+`	Addition	return values which are computed addition of two or more values	`p+q=50`
`-`	Subtraction	return values which are computed subtraction of two or more values	`q-p=10`
`*`	Multiplication	return values which are computed multiplication of two or more values	`p*q=600`
`/`	Divide	Calculate the division of values	`q/p=1.5`
`%`	Modulus	Return the remainder after the division of values	`q%p=10`
`++`	Increment	Increment the value by 1	`++p=21`
`--`	Decrement	Decrement the value by 1	`--q=29`

arithmetic operator Example

Here is an arithmetic operator example

var m = 50;
var n = 20;
console.log(m + n); // returns 70
console.log(m - n); // returns 30
console.log(m * n); // returns 1000
console.log(m / n); // returns 2.5
console.log(m % n); // returns 10
console.log(++m); // returns 51
console.log(--n); // returns 19

Relational Operators in typescript

The Relational operator returns true or false to check operands.

Assume values of M are 10 and N is 20.

Operator	Title	Example
`<`	Less than	`M<N` is false
`>`	Greater than	`M>N` returns false
`<=`	Less than equal	`M<=N` returns false
`>=`	Greater than equal	`M>=N` returns false

Following is a Relational Operator Example

var m = 50;
var n = 20;
console.log(mn); // returns true
console.log(m <= n); // returns false
console.log(m >= n); // returns true

Typescript Equality Operators

These operators check the equality of operands.

assume values of C are 10 and D is 20

Operator	Title	Description	Example
`==`	Equality	returns boolean, first check if types are equal, then compare the values of types are objects, then compares references of the same objects if types are not equal, then it will apply strict comparison	`M==N` returns false
`!=`	Not equal	It will also do the same logic as the above operator with not equal check	`M!=N` returns true
`===`	Identity Operator	This will checks strict equality without doing type conversion	`M!=N` returns true
`!==`	Non Identity	This will check non-strict equality without checking the same types	`M!=N` returns true
