how to replace &,<,> in javascript

Question

In javascript how it's possible to replace all occurrence of &,<,> in a string

I tried this

 var str="<>&";
 str.replace("&","&amp").replace("<","&lt").replace(">","&gt");

but not able to change even first occurrence

replace returns the string so you need to use that variable which is returned by replace...and also this is not javascript — sumeet kumar, Sep 15 '17 at 13:07

The easiest would be to use a regular expression with g flag to replace all instances:

str.replace(/foo/g, "bar")

This will replace all occurrences of foo with bar in the string str. If you just have a string, you can convert it to a RegExp object like this:

var pattern = "foobar",
re = new RegExp(pattern, "g");
