Triple (3) Equal Signs
javascript, jquery
Solution
The triple equal sign in javascript means equality without type coercion.
For example:
1=="1" // true, automatic type coercion
1==="1" // false, not the same type.
Problem
Possible Duplicate: JavaScript === vs == : Does it matter which “equal” operator I use? I asked another question here and received a great answer as follows: ``` $(document).on("keydown", function (e) { if (e.which === 8 && !$(e.target).is("input, textarea") || $(e.target).is('[readonly]')) { e.preventDefault(); } }); ``` Notice the three equal signs `===` in the if-statement. I have always thought you only needed two equal signs `==` for a javascript/jQuery if-statement. Is there any reason for the three? UPDATE Sorry for the duplicate question - I searched but didn't find any good questions. I guess I was using the wrong search terms.
