 1 | # typeOf.js
 2 | 
 3 | typeOf.js is a lightweight and efficient JavaScript Type-checking utility.
 4 | Since, the `typeof` operator in JavaScript is not reliable, i created this utility that efficiently tells the Data Type of a value.
 5 | 
 6 | # Examples
 7 | Below are type-checking examples of common types:
 8 | 
 9 | ```javascript
10 |     typeOf( "Hello world" ); // "string"
11 |     typeOf( 5 ); // "number"
12 |     typeOf([ 1, 2, 3 ]); // "array"
13 |     typeOf({ a: 1, b: 2, c: 3 }); // "object"
14 |     typeOf( function(){} ); // "function"
15 |     typeOf( new Date() ); // "date"
16 |     typeOf( true ); // "boolean"
17 |     typeOf( /.*/ ); // "regexp"
18 |     typeOf( new Error() ); // "error"
19 |     typeOf( null ); // "null"
20 |     typeOf(); // "undefined"
21 |     typeOf( new Symbol() ); // "symbol"
22 |     typeOf( function* gen(){} ); // "generatorfunction"
23 | ```
