What is the best way to substitute multiple words with a single word in javascript?

Suppose I have a sequence of characters:

var str = "aaaa aaa aaaaaa safsd a a a aaaa";

Note: The character a may be repeated several times,

I want to replace all instances of connected as with just one a. For instance, replacing aaaa with a, the desired output from the given str would look like this:

Output: a a a safsd a a a a

Answer №1

If you want to replace multiple occurrences of the letter 'a', you can utilize the

string.replace(regexp, newString)
method along with the regular expression /a+/g.

var str = "aaaa aaa aaaaaa safsd a a a aaaa";

str = str.replace(/a+/g, "a");

console.log(str)

Answer №2

Allow me to offer a modified response to the previous post:

var str = "aaaa aaa aaaaaa safsd a a a aaaa";
str = str.replace(/a{2,}/g, "a");
console.log(str);

In this variation, we are only replacing sequences of two or more a's, leaving single occurrences untouched.
