Ternary operator--javascript Basic tutorial Mark

Ternary operators

Judging the conditions? (The condition is true when executed): (the condition is false)

Contrast memory

var color= ' Red ';

Determine if the color is red

if (color=== ' red ') {

Console.log (' takeout ');

}else {

Console.log (' nothing ');

}

Using ternary operators to implement

color=== ' Red '? Console.log (' takeout '): Console.log (' nothing ');

Note: Complex conditions are not recommended as ternary operators, and it is better to use the IF Else statement directly.
