Explaination : The g in the regular expression (short for global) says to search the whole string rather than just find the first occurrence. This matches 'is' twice.javascript count number of times character appears in string
You could remove any other character in the string and check the length:
str.replace(/[^aA]/g, "").length
Here it is counted how many as are in str. The RegExp is described below:
[ // Start Character Group
^ // Not operator in character group
a // The character "a"
] // End character group
//The g (global) in the regular expression tells the program to search
//the whole string rather than just finding the first occurrence.Copyright © 2021 Codeinu
