Which statements in JS are true by default in the IF statement

　　Conclusion : A function in JS is: the Boolean (value) function converts a value to the corresponding Boolean value.

When value is the following values are true:1. Any non-empty string. 2. Arbitrary non-0 digits

And when value is the following value is False:1. The empty string is (""). 2, 0, and Nan (not a number). 3.undefined

If the above value is written in the IF statement, the browser automatically calls the Boolean (value) function.

For example: if ("Hello World") {

Alert ("Hello");

}

Equivalent to: if (Boolean ("value")) {alert ("Hello");}
