    About Lesson

    Comparison operators are used in logical statements to determine equality or difference between variables or values. JavaScript supports several comparison operators, including:

    • == (Equal to)
    • === (Equal value and equal type)
    • != (Not equal)
    • !== (Not equal value or not equal type)
    • > (Greater than)
    • < (Less than)
    • >= (Greater than or equal to)
    • <= (Less than or equal to)

     

    How to Use Comparison Operators

    Here’s a brief explanation of how each operator works:

     

    Equal to (==)

    The == operator checks if the values of two operands are equal or not. If they are equal, it returns true.

    let x = 5;
console.log(x == 5); // true

     

    Equal Value and Equal Type (===)

    The === operator checks if the values of two operands are equal or not, and also checks the types.

    let x = 5;
console.log(x === "5"); // false

     

    Not Equal (!=)

    The != operator checks if the values of two operands are not equal. If they are not equal, it returns true.

    let x = 5;
console.log(x != 4); // true

     

    Not Equal Value or Not Equal Type (!==)

    The !== operator checks if the values of two operands are not equal, or if their types are not equal.

    let x = 5;
console.log(x !== "5"); // true

     

    Greater Than (>)

    The > operator checks if the value of the left operand is greater than the value of the right operand. If it is, it returns true.

    let x = 5;
console.log(x > 4); // true

     

    Less Than (<)

    The < operator checks if the value of the left operand is less than the value of the right operand. If it is, it returns true.

    let x = 5;
console.log(x < 6); // true

     

    Greater Than or Equal To (>=)

    The >= operator checks if the value of the left operand is greater than or equal to the value of the right operand. If it is, it returns true.

    let x = 5;
console.log(x >= 5); // true

     

    Less Than or Equal To (<=)

    The <= operator checks if the value of the left operand is less than or equal to the value of the right operand. If it is, it returns true.

    let x = 5;
console.log(x <= 5); // true

     

    Using JavaScript’s comparison operators is fundamental to comparing values in your code. They are essential tools in every developer’s toolkit.
