4.2. Type Conversion¶ code example

Example 1: 4.2. Type Conversion¶

/*The type conversion function String turns its argument into a string. 
Remember that when we print a string, the quotes may be removed. 
However, if we print the type, we can see that it is definitely 
'string'.*/

console.log(String(17));
console.log(String(123.45));
console.log(typeof String(123.45));

//17
//123.45
//string

Example 2: 4.2. Type Conversion¶

/*What happens if we attempt to convert a string to a number, and the 
string doesn't directly represent a number?*/

console.log(Number("23bottles"));

//NaN

Example 3: 4.2. Type Conversion¶

/*The Number function can take a string and turn it into an integer. 
Let us see this in action:*/

console.log(Number("2345"));
console.log(typeof Number("2345"))
console.log(Number(17));

//2345
//number
//17
