My code:
function removeFromString(mystring,char){
let regex = new RegExp(char, 'g');
let string;
for(let i; i< mystring.length; i++){
string = mystring.replace(regex, ''));
}
console.log(mystring);
}
removeFromString('Hello How are you','o');
This doesn't work. Any idea what am I doing wrong?
The method String.replace()
doesn't change the string, it creates a new string. Return the result of the replace.
In addition, since you've used the g
flag in the regex, it will replace all occurrences in the string, so you don't need the for loop.
function removeFromString(mystring, char) { const regex = new RegExp(char, 'g'); return mystring.replace(regex, ''); } console.log(removeFromString('Hello How are you', 'o'));
You can also achieve the same thing with a loop, by rebuilding the string from all characters in the original string the are not the char
:
function removeFromString(mystring, char) { let string = ''; for (let i = 0; i < mystring.length; i++) { if(mystring[i] !== char) string += mystring[i]; } return string; } console.log(removeFromString('Hello How are you', 'o'));
You can simply use replace
for it. No need for loop. like
var str = "How are you?"; console.log(str.replace(/o/g, ""))
g
flag is to replace all occurrences
Or Just for fun.
var str = "How are you?"; console.log(str.split("o").join(''))
split
string by your desired character. This will give you an array. Now you can join this array with ''
