Providing comments is good habbit of programming, which helps other developer to understand the code or logic written.
For example if we are writting any comments for variable declaration or brief info then we can use Single line comment.
//count indicates the starting point ( its single line of comments)
var count = 0;
Multiline comments.
/**
* Its multiline comment example
* It will be helpfull for others, what your code is doing.
* It is easy to read. any we can provide logic info.
* response{ [Object] } indicates the array object
* response getting from any service call or locally
* Similary here you can specify for other parts.
*/
function getTotalCount(response){
var count = 0;
for(var value = 0; value < response.lenght; value++ ){
count = count + response["itemsCount"];
}
}
// FOR SINGLE LINE, /* */ FOR MULTI LINE
// for single line and /* */ for multiline
Single Line Comment: //
Multi Line Comments: /* */
To create a single line comment in JavaScript, you place two slashes "//" in front of the code or text you wish to have the JavaScript interpreter ignore. When you place these two slashes, all text to the right of them will be ignored, until the next line.
1.Multiple-line C-style comments. Everything between /* and */ is a comment, for example:
/* This is a comment */ /* C-style comments can span as many lines as you like, as shown in this example */
2.One-line comments of C++ style. These comments begin with // and continue up to the next line break:
// This is a one-line comment
3.One-line comments with the HTML comment-opening sequence (). Consider this example:
This is also a one-line JS comment because JS ignores the closing characters of HTML-style comments
Mainly 3 symbols are use for comments in JavaScript -1 multiline comments /* */ 2- single line of C++ style // 3- single line
