How can I stop the error message Expected '===' and instead saw '=='.
from appearing in jslint.
Doesn't seem to be an option.
For those using JSHint, you can turn off this warning by setting the option eqeqeq to false in your JSHint options (usually .jshintrc)
"eqeqeq": false
From the documentation: http://jshint.com/docs/options/#eqeqeq
Edit:
If you want to be a good citizen and fix your code to use the recommended comparison instead of turning the warning off, make sure both sides of the comparison are using the same type.
For example:
"123" == 123 // true, I'm lazy and JSHint hates me
"123" === 123 // false, no love
Number("123") === 123 // true, no warning
