There is no return statement if !x.isReady is false. Are you sure this is correct? If so, consider adding return; explicitly.

This check looks for functions where a return statement is found in some execution paths, but not in all.

Consider this little piece of code

function isBig(a) {
    if (a > 5000) {
        return "yes";
    }
}

console.log(isBig(5001)); //returns yes
console.log(isBig(42)); //returns undefined

The function isBig will only return a specific value when its parameter is bigger than 5000. In any other case, it will implicitly return undefined.

This behaviour may not be what you had intended. In any case, you can add a return undefined to the other execution path to make the return value explicit.

Comprehensibility introduced by
Usage of the sequence operator is discouraged, since it may lead to obfuscated code.

The sequence or comma operator allows the inclusion of multiple expressions where only is permitted. The result of the sequence is the value of the last expression.

This operator is most often used in for statements.

Used in another places it can make code hard to read, especially when people do not realize it even exists as a seperate operator.

This check looks for usage of the sequence operator in locations where it is not necessary and could be replaced by a series of expressions or statements.

var a,b,c;

a = 1, b = 1,  c= 3;

could just as well be written as:

var a,b,c;

a = 1;
b = 1;

There is no return statement if x.acceptData(e) is false. Are you sure this is correct? If so, consider adding return; explicitly.

This check looks for functions where a return statement is found in some execution paths, but not in all.

Consider this little piece of code

function isBig(a) {
    if (a > 5000) {
        return "yes";
    }
}

console.log(isBig(5001)); //returns yes
console.log(isBig(42)); //returns undefined

The function isBig will only return a specific value when its parameter is bigger than 5000. In any other case, it will implicitly return undefined.

This behaviour may not be what you had intended. In any case, you can add a return undefined to the other execution path to make the return value explicit.

Comprehensibility introduced by
Usage of the sequence operator is discouraged, since it may lead to obfuscated code.

The sequence or comma operator allows the inclusion of multiple expressions where only is permitted. The result of the sequence is the value of the last expression.

This operator is most often used in for statements.

Used in another places it can make code hard to read, especially when people do not realize it even exists as a seperate operator.

This check looks for usage of the sequence operator in locations where it is not necessary and could be replaced by a series of expressions or statements.

var a,b,c;

a = 1, b = 1,  c= 3;

could just as well be written as:

var a,b,c;

a = 1;
b = 1;
c = 3;

To learn more about the sequence operator, please refer to the MDN.

The assignment to i seems to be never used. If you intend to free memory here, this is not necessary since the variable leaves the scope anyway.

There is no return statement if this !== at() && this.focus is false. Are you sure this is correct? If so, consider adding return; explicitly.

This check looks for functions where a return statement is found in some execution paths, but not in all.

Consider this little piece of code

function isBig(a) {
    if (a > 5000) {
        return "yes";
    }
}

console.log(isBig(5001)); //returns yes
console.log(isBig(42)); //returns undefined

The function isBig will only return a specific value when its parameter is bigger than 5000. In any other case, it will implicitly return undefined.

This behaviour may not be what you had intended. In any case, you can add a return undefined to the other execution path to make the return value explicit.

There is no return statement if a = typeof r , "string" ...= s.set(e, r, i) === t) is false. Are you sure this is correct? If so, consider adding return; explicitly.

This check looks for functions where a return statement is found in some execution paths, but not in all.

Consider this little piece of code

function isBig(a) {
    if (a > 5000) {
        return "yes";
    }
}

console.log(isBig(5001)); //returns yes
console.log(isBig(42)); //returns undefined

The function isBig will only return a specific value when its parameter is bigger than 5000. In any other case, it will implicitly return undefined.

This behaviour may not be what you had intended. In any case, you can add a return undefined to the other execution path to make the return value explicit.

Comprehensibility introduced by
Usage of the sequence operator is discouraged, since it may lead to obfuscated code.

The sequence or comma operator allows the inclusion of multiple expressions where only is permitted. The result of the sequence is the value of the last expression.

This operator is most often used in for statements.

Used in another places it can make code hard to read, especially when people do not realize it even exists as a seperate operator.

This check looks for usage of the sequence operator in locations where it is not necessary and could be replaced by a series of expressions or statements.

var a,b,c;

a = 1, b = 1,  c= 3;

could just as well be written as:

var a,b,c;

a = 1;
b = 1;
c = 3;

To learn more about the sequence operator, please refer to the MDN.

console.log(isBig(5001)); //returns yes
console.log(isBig(42)); //returns undefined

The function isBig will only return a specific value when its parameter is bigger than 5000. In any other case, it will implicitly return undefined.

This behaviour may not be what you had intended. In any case, you can add a return undefined to the other execution path to make the return value explicit.
