将双引号替换为单引号？

Question

It may sounds dumb but I don't succeed in replacing every double quotes of a string into simple quotes. Here is what I do:

const str = '1998: merger by absorption of Scac-Delmas-Vieljeux by Bolloré Technologies to become \"Bolloré\".';
console.log(str.replace(`"`, `'`));

And it ouputs :

1998: merger by absorption of Scac-Delmas-Vieljeux by Bolloré Technologies to become 'Bolloré"

What's going on here. I tried many other solutions... It just doesn't work.

Any ideas?

With str.replace() only the first instance of a substring will be replaced. You can use a regular expression and add the global flag to replace all instances.

str.replace(regexp|substr, newSubstr|function)

substr (pattern) A String that is to be replaced by newSubStr . It is treated as a verbatim string and is not interpreted as a regular expression. Only the first occurrence will be replaced.

console.log(str.replace(/\"/g, `'`));
