Hi all ,

I have an array read as a string[]
Now is a huge text with each new words separated with a comma
I want to read and save data, but when a certain word appears I want to stop and just save only save data uptill that point.

here is my code where are my going wrong?
for now everything still gets saved .

JavaScript

var mylist=Somerawdata;
var expectedWords="my name is Garner Eric";
for(let i =0;i<.length;i++){
if(mylist[i]===expectedWords)break
console.log(mylist[i]);
}

What I have tried:

var mylist=Somerawdata;
var expectedWords="my name is Garner Eric";
for(let i =0;i<.length;i++){
if(mylist[i]===expectedWords)break
console.log(mylist[i]);
}

For anyone looking at this after following suggestions from

JavaScript

<pre>var mylist=Somerawdata;
var expectedWords="my name is Garner Eric";
for(let i =0;i<.length;i++){
if(mylist===expectedWords)

mylist.substring(0, mylist.indexOf(expectedWords));
console.log(mylist);

You need to do something to split the input data at the word break positions. As it stands Javascript is treating your input as an array of single characters, so it will never find your match string.

You may find that Regular expressions - JavaScript | MDN[^] would be a better solution.

Solution 2

You may wish to consider the javascript indexOf() method.

It returns the index value of the match ( >= 0) or a -1 if not found.

So, you can the handle the string by saving it's contents up to the found index or the entire string (if -1). Use the substring() method.

I'll leave the actual coding to you as it will reinforce the methods in your memory.

I do not write code for you - I tell you what needs to be done and possibly things to consider. You will learn nothing if I do it for you.

Telling you the methods to use has given you the answer. Computer programming requires effort - at least if you really want to do computer programming.

Think about why I picked out those two methods - how will they help? Solving problems takes practice - not google.

Sir I have implemented the method you suggested below and it worked as expected
Thnk you for the directions

var mylist=Somerawdata;
var expectedWords="my name is Garner Eric";
for(let i =0;i<.length;i++){
if(mylist===expectedWords)

mylist.substring(0, mylist.indexOf(expectedWords));
console.log(mylist);
}
