const source = "abcdefabcdef";
const str1 = "abc", str2 = "xyz";
const reg1 = /abc/g, reg2 = "xyz";

//Case 1 : When we want to replace a string by another
console.log(source.split(str1).join(str2));
console.log(source.replace(new RegExp(str1,"g"),str2));
//versus
console.log(source.replaceAll(str1,str2));

//Case 2 : When we want to use a regular expression
console.log(source.replace(reg1,reg2));
//versus
console.log(source.replaceAll(reg1,reg2));

//Result = "xyzdefxyzdef"
