let s1MB = "0123456789".repeat(1000*100);
var strings1MB = Array.from(Array(20)).map(o=>s1MB + String.fromCharCode(32+~~(Math.random()*96)))
Tests:

  • string comparison

     
    const s1 = strings1MB[~~(strings1MB.length*Math.random())];
    const s2 = strings1MB[~~(strings1MB.length*Math.random())]+"a";
    const b = s1 === s2;

  • string length comparison

     
    const s1 = strings1MB[~~(strings1MB.length*Math.random())];
    const s2 = strings1MB[~~(strings1MB.length*Math.random())]+"a";
    const b = s1.length === s2.length;
