how to replace all occurrences of a string in javascript

// Update: In the latest versions of most popular browsers,
// you can use replaceAll as shown here:
let result = "1 abc 2 abc 3".replaceAll("abc", "xyz");
// `result` is "1 xyz 2 xyz 3"

/*
For Node and compatibility with older/non-current browsers:
Note: Don't use the following solution in performance critical code.
As an alternative to regular expressions for a simple literal string, 
you could use:
*/
str = "Test abc test test abc test...".split("abc").join("");

// ass a general pattern
// str.split(search).join(replacement)

javascript regex replace

const search = 'duck'
const replaceWith = 'goose';

const result = 'duck duck go'.replaceAll(search, replaceWith);

result; // => 'goose goose go'
