What is the difference between the == and === operators in JavaScript?

  • == compares values for equality, === compares values and types for equality
  • == compares values and types for equality, === compares values for equality
  • == is used for assignment, === is used for comparison
  • == performs a deep comparison, === performs a shallow comparison
In JavaScript, == (loose equality) compares values for equality but performs type coercion if the operands have different types. === (strict equality) compares both values and types for equality without type coercion. Option 1 correctly describes this important distinction.
