1 . Less than ( <\/em><\/strong><<\/strong><\/span><\/em> )<\/em><\/strong> :-<\/em><\/strong> This operation will return TRUE <\/strong>when the expression will be satisfied and FALSE <\/strong>when not satisfied. See the Below Example

var a = 5<2<\/strong> ;
document.write(a) ;

OUTPUT<\/strong> :-<\/strong><\/em> False<\/strong><\/span><\/p>\n\n\n\n

2 . Greater than ( ><\/span> )<\/em><\/strong> :-<\/em><\/strong> This operation will return TRUE <\/strong>when the expression will be satisfied and FALSE <\/strong>when not satisfied. See the Below Example

var a = 5>2<\/strong> ;
document.write(a) ;

OUTPUT<\/strong> :-<\/strong><\/em> True<\/strong><\/span><\/p>\n\n\n\n

3 . Less than or Equal to ( <=<\/span> )<\/em><\/strong> :-<\/em><\/strong> When 1st element is Less than<\/em><\/strong> or Equal to <\/em><\/strong>the other element then it returns TRUE <\/strong>otherwise FALSE<\/strong>. See the Below Example

var a = 5<=2<\/strong> ;
document.write(a) ;

OUTPUT<\/strong> :-<\/strong><\/em> False<\/strong><\/span><\/p>\n\n\n\n

4 . Greater than or Equal to ( >=<\/span> )<\/em><\/strong> :-<\/em><\/strong> When 1st element is Greater than <\/em><\/strong>or Equal to<\/em><\/strong> the other element then it returns TRUE <\/strong>otherwise FALSE<\/strong>. See the Below Example

var a = 5>=2<\/strong> ;
document.write(a) ;

OUTPUT<\/strong> :-<\/strong><\/em> True<\/strong><\/span><\/p>\n\n\n\n

5 . Equal to ( ==<\/span> )<\/em><\/strong> :-<\/em><\/strong> When 1st element is Equal to<\/em><\/strong> the other element then it returns TRUE <\/strong>otherwise FALSE<\/strong>. See the Below Example

var a = 5==2<\/strong> ;
document.write(a) ;

OUTPUT<\/strong> :-<\/strong><\/em> False<\/strong><\/span><\/p>\n\n\n\n

6 . Not Equal to ( !=<\/span> )<\/em><\/strong> :-<\/em><\/strong> When 1st element is Not Equal to<\/em><\/strong> the other element then it returns TRUE <\/strong>otherwise FALSE<\/strong>. See the Below Example

var a = 5!=2<\/strong> ;
document.write(a) ;

OUTPUT<\/strong> :-<\/strong><\/em> True<\/strong><\/span><\/p>\n\n\n\n

7 . Equal Value and Same Type ( ===<\/span> )<\/em><\/strong> :-<\/em><\/strong> When 1st element is Equal to<\/em><\/strong> and of the Same Type<\/em><\/strong> to the other element then it returns TRUE <\/strong>otherwise FALSE<\/strong>. See the Below Example

var a = 5===5<\/strong> ;
document.write(a) ;

OUTPUT<\/strong> :-<\/strong><\/em> True<\/strong><\/span>
Note :- <\/em><\/strong> in the above example the elements are of equal value and same type, so it returns TRUE<\/strong>.
————————————————————————————————–
var a = 5===”5″<\/strong> ;
document.write(a) ;

OUTPUT<\/strong> :-<\/strong><\/em> FALSE<\/span><\/strong>
Note :-<\/em><\/strong> in the above example the elements are of equal value but not of same type, so it returns TRUE<\/strong>.<\/p>\n\n\n\n

8 . Not Equal Value or Not Same Type ( ===<\/span> )<\/em><\/strong> :-<\/em><\/strong> When 1st element is Not<\/em><\/strong> Equal to<\/em><\/strong> or Not<\/strong> Same Type<\/em><\/strong> to the other element then it returns TRUE <\/strong>otherwise FALSE<\/strong>. See the Below Example

var a = 5!==5<\/strong> ;
document.write(a) ;

OUTPUT<\/strong> :-<\/strong><\/em> FALSE<\/strong><\/strong><\/span>
Note :- <\/em><\/strong> in the above example the elements are of equal value or the same type, therefore it can’t satisfy the expression and returns FALSE<\/strong><\/strong>.
————————————————————————————————–
var a = 5!==”5″<\/strong> ;
document.write(a) ;

OUTPUT<\/strong> :-<\/strong><\/em> TRUE<\/strong><\/span><\/strong>
Note :-<\/em><\/strong> in the above example the elements are of equal value but not of same type, therefore it satisfies the expression and returns TRUE<\/strong>.<\/p>\n\n\n\n
