How to replace all \ char into ' in javascript

Question

if, a = "Bob\'s house"

how would you replace the backslash with another '? I want a to equal "Bob''s house"

I would assume that I can do a.replace("\", "'") but this doesn't work

Press [F12], enter `"Bob\'s house"` into the console and inspect the result - there is no "\" <-- this is an escape character. If you would define `a = "Bob\\'s house"`, then it would work. But this seems somewhat nonsensical to me. How about `a.replace("'", "''")`? — le_m, Jun 04 '17 at 23:06

It does not work because \' is treated as a single character. In Javascript \ is used to initiate an escape character, which means "literally the character after \".

In order to show \ you therefore need to write \\. And if you want to change escaped ' into '' what you need to do is simply a.replace("\'", "\'\'");

basically a = "Bob\'s house" is interpreted as "Bob's house", youre just escaping the '. there is no backslash in the string.

to have your wanted result ("Bob''s house"), simply do the following:

a.replace("\'", "\'\'")

as user2182349 said, a.repalce("\\", "'") did the trick
