<\/span><\/h2>\n\n\n\nEvery JavaScript string supports replace() function that basically allows you to replace the first occurrence of a character in string. Here is its syntax.<\/p>\n\n\n\n
string.replace(old_character,new_character);<\/pre>\n\n\n\nTo remove a character from a string, you can simply replace it with empty character ”. Here is an example to replace the first occurrence of letter ‘o’ in ‘good morning’.<\/p>\n\n\n\n
var a = 'good morning';
res = a.replace('o','');
console.log(res); \/\/ output is 'god morning'<\/pre>\n\n\n\nYou can use replace function with string variables as well as literal strings. Here is an example using literal strings.<\/p>\n\n\n\n
res='good morning'.replace('o','');
console.log(res); \/\/ output is 'god morning'<\/pre>\n\n\n\nIf you want to replace all occurrences of a character then you need to specify a regular expression instead of a literal character by enclosing with within \/…\/g<\/p>\n\n\n\n
var a = 'good morning';
var result=a.replace(\/o\/g,'');
console.log(result); \/\/ output is gd mrning<\/pre>\n\n\n\n
