So basically I want to delete string from txt file.
using fs
Input Example:
string1
string2
string3
string4
Delete string3
After delete It would be like:
string1
string2
string4
Read the text file get the content in a variable then use String.replace
For example
var stringContent="Here goes the content of the textFile after read"
var res=stringContent.replace('string3','');
//write back res to the file or do what ever
As brk answered, replace method on string will do the job.
Another way is
var a = new Array();
a = string.split("searching_string");
string = a.join("");
Think it should work. But why do you make it complex when replace exists?
