Javascript Practice 22: JS Hero - String: trim()

 

Question: 

 

Write a function firstChar, which returns the first character that is not a space when a string is passed.

Example: firstChar(' Rosa Parks ') should return 'R'.

 

 

 

 

Answer: 

 

 function firstChar (input) {

let x = input.trim();
return x.charAt(0);

}; 

 

> function expression

> function name is firstChar

>  parameter is input

> declared a variable x and initialized it with a value

> value is a trimmed version of the input parameter

> used the trim() method to remove whitespaces from both the ends of a string (in this case the input parameter)

>  when the function firstChar is called, using an argument that has empty spaces on both ends, it will return the first character after trimming the empty spaces

> the first character is accessed by using the charAt(0) method.
