We shipped a couple of exciting new features in October. Here's a short write-up about some of them.
Thanks to Daniel Miladinov, JSHint can now ignore blocks of code which makes it easier to use JSHint with JavaScript language extensions such as Facebook React.
// Code here will be linted with JSHint.
/* jshint ignore:start */
// Code here will be linted with ignored by JSHint.
/* jshint ignore:end */All code in between ignore:start and ignore:end won't be passed to JSHint at all. Additionally, you can ignore a single line with a trailing comment:
ignoreThis(); // jshint ignore:lineThanks to Oleg Grenrus, JSHint can now check the use of a typeof operator when its result is compared to a string. This operator has only a limited set of possible return values (mdn). If you try to compare it with an invalid value, JSHint will produce a warning informing you about the issue. You can disable this check with a notypeof option.
// 'fuction' instead of 'function'
if (typeof a == "fuction") { // Warning: Invalid typeof value 'fuction'
/* ... */
}Thanks to Caitlin Potter, there's a new option—freeze—that prohibits the modification of native objects such as Array, Number, Date, etc. It's generally a bad idea to modify these objects unless you're absolutely sure you know what you're doing.
/* jshint freeze:true */
Array.prototype.count = function (value) { return 4; };
// -> Warning: Extending prototype of native object: 'Array'.This option is still under development. Do you have suggestions on how we can improve it? Tell us here.
We now use GitHub releases to host our changesets:
