ternary inside ternary code example

Example 1: ternary operator

(condition) ? (if true, do this) : (otherwise, do this)

Example 2: nested ternary operator javascript

function example(…) {
    return condition1 ? value1
         : condition2 ? value2
         : condition3 ? value3
         : value4;
}

// Equivalent to:

function example(…) {
    if (condition1) { return value1; }
    else if (condition2) { return value2; }
    else if (condition3) { return value3; }
    else { return value4; }
}

Example 3: ternary

isMember ? '$2.00' : '$10.00'
// isMember true =>  output: "$2.00"

// isMember false =>  output: "$10.00"

// isMember null =>  output: "$10.00"
