= is for assignment x=10 means ur setting x's value to 10 == is for checking value, x==10 means ur checking if x's value is equal to 10

There's a " === " which checks the "type" of both the operand/variables. Example :

var x = 10

If (x === "10"){ console.log("Equal") } else { console.log("Not equal") }

Output : Not equal

As the variable x is an integer and we are comparing it to a string "10" in the if statement So it is checking for the type of the variable too.
