Benchmark: switch vs dictionary lookup

Script Preparation code:

var getCursorClass = (state) => {
    switch (state) {
        case 'pending':
            return 'cursor-wait';
        case 'disabled':
            return 'cursor-not-allowed';
        default:
            return 'cursor-pointer';
    }
}

var cursorClassDict = {
    'pending': 'cursor-wait',
    'disabled': 'cursor-not-allowed',
    'default': 'cursor-pointer'
}
var states = ['pending','disabled', 'default'];

Tests:

Switch
const state = states[Math.floor(Math.random()*states.length)]; return getCursorClass(state)
Dict
const state = states[Math.floor(Math.random()*states.length)]; return cursorClassDict[state]
