After an hour of debugging, realised that I wrote =+ instead of +=.

I will just to go in a corner and cry for a minute. brb guys.

I feel you... Want a tissue?

what IDE?

Both are valid in js (if thats the lang your using) I suggest a formatting standard. Infact the format named standard is really great. It will help you catch stuff like that in the future.

@IllSlapU
variable += 1
Compiler says nothing, variable will be increment by one normally, not an error of any kind.

variable =+ 1
Can be seen as "variable = +1", variable will be set to 1, no syntax error, whatsoever.

@IllSlapU it did not warn me. See the explanation by @Gatgeagent.

@appinv not an IDE. VSCode

@jamesharrington it's c++, not JS.

@tahnik try netbeans for cpp

This one guy asked me to debug his code. Apparently he didn't put braces after a for loop and expected the compiler to read his mind. After I told him to correct it, he wrote the braces first and put the looping condition inside the braces.

In his defense, he is just learning and not a CS student.

Wow, dumb language, dumb tools.

@Hastouki
Nah, just dumb tools. A decent compiler will warn you.
