36. Javascript comparison operators and conditional operators – Full stack web development Course

In this FullStackWebDevelopment tutorial series video, We will learn about #javascript #comparison #operators and if/else #conditional operators. These allow the code to make smart decisions. The several comparison operators used in javascript are (for eg x=7;)

A) == checks if two variables have equal value.
Example:
x==8 false
x==7 true
x==’7’ true

B) === Checks for equal value and equal type
Example:
x==8 false
x==7 true
x==’7’ false

C) != Checks for value Not equal
Example:
x!=8 true

D) !== Checks for Not equal value or not equal type
Example:
x!==’8’ true
x!==8 true
x!==7 false

E) (Left angle bracket) Checks for Value Greater than
Example:
x(Left angle bracket) 8 false

F) (Right angle bracket) Checks for Value Less than
Example:
x(Right angle bracket) 8 true

G) (Left angle bracket) = Checks for Value greater than or equal to
Example:
x(Left angle bracket) =8 false

H) (Right angle bracket)= Checks for Value Less than or equal to
Example:
x(Right angle bracket)=8 true

If-else statement:
The if/else statement executes a block of code if a specified condition is true. If the condition is false, another block of code can be executed.The if/else statement is a part of JavaScript’s “Conditional” Statements, which are used to perform different actions based on different conditions.

– if is used to specify a block of code to be executed, if a specified condition is true.
– else if is used to specify a new condition to test, if the first condition is false.
– else is used to specify a block of code to be executed, if the same condition is false and no other else if, if present is true.
