For that, we have to pass two parameters to forEach(). This loop will provide us with two things: the element itself from the array and the element’s index. To print the entire object from the above array, you can use a forEach() loop. Later we will see how to access individual values that are present inside the object. With this, we can loop through each element present inside the for a loop.įirst, let’s access the entire objects using forEach() from the array. The traditional way of finding objects in an array is by using a forEach() loop. Search Objects in an Array Using forEach() in JavaScript There are few ways by which you can find objects in an array. I recommend using string.replaceAll() to replace strings. Unfortunately, you cannot easily generate regular expressions from a string at runtime, because the special characters of regular expressions have to be escaped.įinally, the string method string.replaceAll(search, replaceWith) replaces all string occurrences. This approach works, but it's hacky.Īnother approach is to use string.replace(/SEARCH/g, replaceWith) with a regular expression having the global flag enabled. The first approach to replacing all occurrences is to split the string into chunks by the search string and then join back the string, placing the replace string between the chunks: string.split(search).join(replaceWith).

If search argument is a non-global regular expression, then replaceAll() throws a TypeError exception.

If search argument is a string, replaceAll() replaces all occurrences of search with replaceWith, while replace() replaces only the first occurence.

The string methods replaceAll(search, replaceWith) and replace(search, replaceWith) work the same way, except 2 things: 3.1 The difference between replaceAll() and replace() Note that browser support for this method is currently limited, and you might require a polyfill.

String.replaceAll(search, replaceWith) is the best way to replace all string occurrences in a string 'duck duck go'.replaceAll(' ', '-') replaces all occurrences of ' ' string with '-'.
