| ’var’ keyword was introduced in JavaScript code from the beginning Stage itself. | ‘let’ keyword is introduced in 2015 only. |
| ’Var’ keyword has function scope. The variable defined with var is available anywhere within the function | A variable declared with ‘let’ keyword has scope only within that block. So, let has a Block Scope. |
| The variable declared with ‘var’ be hoisted | The variable declared with ‘let’ be hoisted |
