JavaScript Operators<\/strong><\/p>\n

An operator in javascript is a symbol or keyword that performs some sort of calculation. JavaScript uses different types of operators:<\/p>\n

Arithmetic<\/p>\n

Assignment<\/p>\n

Comparison<\/p>\n

Logical<\/p>\n

Bitwise<\/p>\n

Special<\/p>\n

 <\/p>\n

Arithmetic Operators:<\/strong><\/p>\n

Addition (+), subtraction (-), multiplication (*), Division (\/), modulus (%), increment (++) pre and post, decrement (–) pre and post<\/p>\n

Type coercion is attempting to change the data type when deemed necessary.<\/p>\n

var x = 10; Number<\/p>\n

var y = 1.23; Decimal<\/p>\n

document.write(x+y) will display 11.23 result is decimal<\/p>\n

 <\/p>\n

var x = 10; Number<\/p>\n

var y = \u201c1\u201d; String<\/p>\n

document.write(x+y) will display 101 result is string<\/p>\n

 <\/p>\n

Unary +<\/p>\n

var x = 10; Number<\/p>\n

var y = \u201c1\u201d; String<\/p>\n

var z = x + (+y); the y string is coerce in to number and result is 11<\/p>\n

Assignment Operators<\/strong><\/p>\n

= , += , -= , *= , \/= , %=<\/p>\n

 <\/p>\n

Comparison Operators<\/strong><\/p>\n

== example 4==3 false \u201c4\u201d == 4 is true coercion, 1 = true is true, \u201ccar\u201d == \u201cCar\u201d false<\/p>\n

!= not equal to<\/p>\n

=== (strict equal to) true if both sides are equal and of same type (no coercion is performed)<\/p>\n

!== (strict not equal to)<\/p>\n

><\/p>\n

<<\/p>\n

>=<\/p>\n

<=<\/p>\n

 <\/p>\n

Logical Operators<\/strong><\/p>\n

&&<\/p>\n

||<\/p>\n

!<\/p>\n

 <\/p>\n

Bitwise Operators<\/strong><\/p>\n

&<\/p>\n

|<\/p>\n

^ XOR<\/p>\n

~ not<\/p>\n

<< Left shift<\/p>\n

>> right shift<\/p>\n

 <\/p>\n

Special Operators<\/strong><\/p>\n

?: conditional\u00a0\u00a0 x<y?10:20<\/p>\n
