    This inspection reports usages of JavaScript equality operators which may cause unexpected type coercions. It is considered a good practice to use the type-safe equality operators === and !== instead of their regular counterparts == and !=.
    Depending on the option selected, this will either highlight:
    All usages of == and != operators.
    All usages except comparison with null. Some code styles allow using x == null as a replacement for x === null || x === undefined.
    Only suspicious expressions, such as: == or != comparisons to 0, '', null, true, false, or undefined.

    意思是 == 是个 BUG,请用 ===
    JS 就是这么坑
