JavaScript Strict Mode (“use strict”) Restrictions 1. No implicit global variables - Variables must be declared using let, const, or var 2. ‘this’ is undefined in functions - In normal functions, ‘this’ does not refer to global object 3. No duplicate parameter names - Function parameters must be unique 4. Cannot delete variables or functions - delete keyword cannot be used on declared variables 5. Octal literals are not allowed - Example: 010 is invalid 6. Octal escape sequences are not allowed - Example: “\012” is invalid 7. ‘with’ statement is not allowed 8. Cannot assign to read-only properties 9. Cannot add properties to non-extensible objects 10. eval() has its own scope - Variables inside eval do not leak outside 11. arguments object restrictions - No sync between parameters and arguments 12. Reserved keywords cannot be used as variable names - Examples: let, private, public, interface, etc. 13. Cannot assign to NaN, Infinity, or undefined 14. arguments.callee is not allowed 15. caller and callee access is restricted 16. Safer and stricter function declarations inside blocks 17.
