The alternative realization of IF in JS

Accidentally found an interesting blog "JS using short-circuit principle shorthand if statement" using && short-circuit to achieve the abbreviation of IF.

such as 1==2&&a1=1, the subsequent a1=1 will not be judged, 1==1&&a1=1 will be assigned and go to the return value of the expression.

As multi-line expression? As long as you continue with the && operation, and the preceding expression is true.

Such as:

  if (1==1) {     a1=1;     a2=2; }

The && operation can be written as:

1==1&& (a1=1| | true) && (a2=2)

If it is more, set the previous expression to True

1==1&& (a1=1| | true) && (a2=2| | true) && (a3=3)
