Comparison Operators

Used to compare two values:

  • == (Equal): 5 == ‘5’ (true due to type coercion)
  • === (Strict equal): 5 === ‘5’ (false, no type coercion)
  • != (Not equal)
  • !== (Strict not equal)
  • <, >, <=, >= (Less than, greater than, etc.)

Example:

JavaScript
let a = 5;
let b = '5';
let c = 10;

// == (Equal with type coercion)
console.log(a == b);  // true (5 is equal to '5' because of type coercion)

// === (Strict equal, no type coercion)
console.log(a === b); // false (5 is not strictly equal to '5' because their types are different)

// != (Not equal with type coercion)
console.log(a != b);  // false (5 is considered equal to '5' with type coercion)

// !== (Strict not equal, no type coercion)
console.log(a !== b); // true (5 is not strictly equal to '5' because of type difference)

// < (Less than)
console.log(a < c);   // true (5 is less than 10)

// > (Greater than)
console.log(c > a);   // true (10 is greater than 5)

// <= (Less than or equal)
console.log(a <= b);  // true (5 is equal to '5' with type coercion)

// >= (Greater than or equal)
console.log(c >= a);  // true (10 is greater than 5)
