Lets learn about javascript operators,
For Operators, We can take example of math operators like we already know plus minus divide and all.
So, I start from Math Operators in javascript.
Now define a variable,
Var yearJohn = 2018 - 28;
console.log(yearJohn);
So its is math operator.
I start from plus, multiple, divide and minus operator they both are part of Math operators.
Math Operators
Var year, yeahJohn, yearMark;
now=2018;
yearJohn = now - 28;
yearJohn = now - 38;
console.log(yearJohn);
console.log(now +2);
console.log(now *2);
console.log(now /2);
Logical operators
Now I define two javascript variable.
Var johnAge = 28;
Var markAge = 38;
Var olderAge = johnAge less then markAge;
Typeof Operator
console.log(olderAge);
Its a bollen variable os is a boolean variable
console.log(johnAge);
console.log(‘This is mark new age’);
Var x;
console.log(typeof x);
