How to Replace All Occurrences of a String using Javascript Replace Function

Replace All Occurrences of a String using Javascript

In the second method where we used regular expression, if we identify the regular expression as a global regular expression we can easily replace all occurrences of a string within an other string value in a given text using Javascript.

How we can enable global regular expression is as simple as adding the "g" identifier following the regular expression.
Using "g" following the regular expression pattern, builtin javascript replace method will replace all matches and all occurences of the given text variable with the new string.

var string_variable;
string_variable = "Replace text using javascript replace function within a javascript string variable";
string_variable = string_variable.replace(/javascript/g, "js");
As you can see in the sample javascript codes the implementation or the usage of the replace javascript function is so simple.
