Javascript Practice 26: JS Hero - String: replace()

 

Question: 

Write a function normalize, that replaces '-' with '/' in a date string.

Example: normalize('20-05-2017') should return '20/05/2017'.

Answer: 

function normalize (datestring) {

let a = datestring.replace ('-', '/');

let b = a.replace ('-', '/'); 

return b;

 

};

> we then declare another variable 'b'

> we initialize it with the value we get by using the replace() method on variable 'a' which has the updated datestring

> this time the second occurence of '-' on the datestring is replaced with '/' 

> we return the variable b to get our answer
