Uh hello guys, welcome to this video. So
0:02
in this video I will show you one VS
0:04
code extension which will help you
0:06
highlight your errors in a very human
0:09
friendly way. It will highlight error
0:12
messages and it will also show you what
0:15
error cost. So if you just type for this
0:18
extension which is error lengths this is
0:21
the name of the extension. It's used by
0:23
almost 7 million developers. It's
0:26
developed by this person Alexander. Just
0:29
type this on search bar error lens the
0:32
very first extension which comes right
0:33
here. So simply install this extension.
0:36
It actually helps you highlight your
0:39
errors in a more human friendly way. It
0:42
will also show you as you can see this
0:45
is my JavaScript file here. So it is I
0:48
didn't put any kind of expression here.
0:50
So that's why it is highlighting this by
0:53
using a red background color and also
0:54
showing you the error message that
0:56
expression expected. If I fix this now,
0:59
you can see the error will go away and
1:02
it is valid for each and every
1:04
programming language. Let's suppose in
1:05
this PHP file if I remove this
1:07
semicolon, this error message will put
1:11
in. You will see semicolon expected
1:13
syntax error unexpected and of line
1:16
expecting. So if I fix it, it will go
1:18
away. Same goes with C C++ files as
1:22
well. If I remove the semicolon, you
1:24
will actually see this will highlight
1:26
this section and it will tell you
1:28
exactly what caused the error and it
1:30
will also say you need to put a
1:32
semicolon. So you will actually see. So
1:36
this is a very great extension that I
1:38
found and I use it daily whenever I'm
1:41
doing development. So it actually tells
1:44
you where exactly the error has happened
1:47
and uh it will save you a lot of time as
1:49
well because you no longer need to
1:52
troubleshoot your program and find out
1:53
where the error has taken place. It will
1:55
pinpoint the location and then it will
1:57
tell you and using this highlighting
1:59
feature. So you can use this extension
2:02
error links. So I simply install it and
2:04
start using it. So it's very simple and
2:08
uh you can use this. So, thank you very
