🚀 var vs let vs const in JavaScript! 🤔 Ever wondered which one to use and why? Here's a quick breakdown with examples! 💡 ✅ var – Function scoped, can be redeclared, hoisted with undefined. ✅ let – Block scoped, can't be redeclared, safer than var. ✅ const – Block scoped, can't be reassigned but objects/arrays can be modified.

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. Prevents silent errors by throwing exceptions #JavaScript #StrictMode #WebDevelopment #FrontendDevelopment #codingtips
