Would someone be able to explain the fundamental syntax for reading and writing text files, also known as file handling in TypeScript? If there is a corresponding link that anyone could provide, it would be greatly appreciated.

To incorporate a method called readTextFile into your class, simply follow these steps using Javascript.
readTextFile(file) {
var rawFile = new XMLHttpRequest();
rawFile.open("GET", file, false);
rawFile.onreadystatechange = function ()
{
if(rawFile.readyState === 4)
{
if(rawFile.status === 200 || rawFile.status == 0)
{
var allText = rawFile.responseText;
console.log(allText); // This will display the contents of the file
}
}
}
rawFile.send(null);
}
After defining the method, you can call it by specifying the path of the file as a string.
this.readTextFile(path_of_the_file_to_be_read_as_string);
In the line above, note that this refers to the context from which the function is being called.
Although Javascript allows us to read files, writing into files is not supported. Learn more at:
